iw3620 24V300mA LED driver test report

DESCRIPTIONIS32FL3238 is an LED driver with 18 constant current channels. Each channel can be pulse width modulated (PWM) by 16 bits for smooth LED brightness control. In addition, each channel has an 8-bit output current control register which allows fine tuning the current for rich RGB color mixing, e.g., a pure white color LED application. The maximum output current of each channel is designed to be 76mA, which can be adjusted by one 8-bit global control register. Proprietary programmable algorithms are used in IS32FL3238 to minimize audible noise caused by the MLCC decoupling capacitor. All registers can be programmed via a high speed I2C (1MHz).FEATURES∙ 2.7V to 5.5V VCC supply∙Modulate LED brightness with256/1024/4096/65536 steps PWM method∙Modulate LED DC current with 256 steps method ∙Global 256 steps analog global current control∙PWM frequency selectable∙Open short detect function∙Spread spectrum∙WFQFN-28 (5mm×5mm) and eTSSOP-28 packagesQUICK STARTFigure 1: Photo of IS32FL3238-ZLS4 Evaluation Board RECOMMENDED EQUIPMENT∙ 5.0V, 2A power supplyABSOLUTE MAXIMUM RATINGS∙≤ 5.5V power supplyCaution: Do not exceed the conditions listed above, otherwise the board will be damaged.PROCEDUREThe IS32FL3238 evaluation board is fully assembled and tested.

Read and follow all of Whelen’s written instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without taking their eyes off the roadway. Emergency warning devices can require high electrical voltages and/or currents. Properly protect and use caution around live electrical connections.Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or vehicle damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference. Therefore, after installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.Warnings to UsersWhelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and operated in accordance with the standards established by the National Fire Protection Association.Safety FirstThis document provides all the necessary information to allow your Whelen product to be properly and safely installed.

Actuator sizing should be done in accordance with the damper manufacturer’s specifications.The default parameters for 2 to 10 VDC applications of the …MFT actuator are assigned during manufacturing. If necessary, custom versions of the actuators can be ordered. The parameters can be changed by two means: pre-set and custom configurations from Belimo or on-site configurations using the Belimo PC-Tool software.The actuator is not provided with and does not require and limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.The LHX series provides 4, 8, or 12 in of linear force. The stroke of the gear rack can be adjusted on both sides in increments of 0.8 in [20 mm] by means of the mechanical end stops.When reaching the damper or actuator end position, the actuator automatically stops.The gears can be manually disengaged with a button on the actuator cover.The LHX24-MFT… actuators use a sensorless brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.Proportional control damper actuators shall be electronic type, which require no crank arm and linkage. Actuators must provide proportional damper control in response to a 2 to 10 VDC or, with the addition of a 500 Ω resistor, a 4 to 20 mA control input from an electronic controller or positioner. Actuators shall have brushless DC motor technology and be protected from overload at all angles of rotation. Actuators shall have reversing switch and manual override on the cover. Run time shall be constant and independent of torque. A 2 to 10 VDC feedback signal shall be provided for position indication. Actuators shall be cUL Approved, have a 5-year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo.AccessoriesElectrical accessoriesDescriptionType DC Voltage Input Rescaling ModuleIRM-100Convert Pulse Width Modulated Signal to a 2...10 V Signal for Belimo Proportional ActuatorsPTA-250Positioner for wall mountingSGA24Positioner for front-panel mounting SGF24Cable conduit connector 1/2"TF-CC US Gateway MP to BACnet MS/TP UK24BAC Gateway MP to LonWorks UK24LON Gateway MP to Modbus RTUUK24MOD Resistor, 500 Ω, 1/4" wire resistor with 6" pigtail wires ZG-R01Resistor kit, 50% voltage dividerZG-R02Transformer, AC 120 V to AC 24 V, 40 VAZG-X40Battery backup system, for non-spring return models NSV24 US Battery, 12 V, 1.2 Ah (two required)NSV-BATMechanical accessoriesDescriptionType Ball joint suitable for damper crank arm KH8 / KH10, Multipack 10 pcs.KG10A Ball joint suitable for damper crank arm KH8, Multipack 10 pcs.KG6Ball joint suitable for damper crank arm KH8, Multipack 10 pcs.KG8Push rod for KG6 & KG8 ball joints (36” L, 5/16” diameter).SH8Rotary support, for linear actuator, for compensation of transverse forces Z-DS13/8”-16 shaft clevis for AHK/AH.Z-KSC Bracket for AHK/AH/LH linear actuators.ZG-119ToolsDescriptionType Belimo PC-Tool, Software for adjustments and diagnostics MFT-P Signal simulator, Power supply AC 120 VPS-100Connecting cable 16 ft [5 m], A: RJ11 6/4 ZTH EU, B: 6-pin for connection to service socketZK1-GEN Connecting cable 16 ft [5 m], A: RJ11 6/4 ZTH EU, B: free wire end for connection to MP/PP terminalZK2-GEN Connecting cable 10 ft [3 m], A: RJ11 6/4 ZTH EU, B: 3-pin Weidmüller and supply connectionZK4-GEN Service Tool, with ZIP-USB function, for programmable andcommunicative Belimo actuators, VAV controller and HVAC performance devicesZTH USElectrical installationActuators with appliance cables are numbered.Provide overload protection and disconnect as required.Actuators may also be powered by DC 24 V.Only connect common to negative (-) leg of control circuits.A 500 Ω resistor (ZG-R01) converts the 4...20 mA control signal to 2...10 V.Control signal may be pulsed from either the Hot (Source) or Common (Sink) 24 V line.For triac sink the Common connection from the actuator must be connected to the Hotconnection of the controller.
