Parameter
Details
Full model / series
LPF-90D-54 / LPF-90D
Model code
LPF-90D identifies this series; the final voltage code 54 identifies the 54 V output version.
Output mode and load selection
Directly drives a compatible LED load at 1.67 A within 32.4-54 V. Use the D-type dimming interface below; this driver is not suitable for use with an additional LED driver.
Load limits
Do not exceed 1.67 A or 90.18 W; apply input and temperature derating. Use the actual rated power, not the series number, for load sizing.
Applications
LED panel lighting, downlights, decorative lighting, tunnel lighting and moving signs. The manufacturer lists Type HL use in Class I, Division 2 hazardous (classified) locations; suitability of the completed installation remains subject to its applicable assessment.

Dimming and external controls
Parameter
Details
3-in-1 interface
Adjust the constant current level between DIM+ and DIM- using one of: additive 1-10 VDC, a 10 V PWM signal, or resistance. Typical dimming source current from the driver is 100 µA.
Analog voltage
The plotted range is 1-10 VDC for 10-100% output current.
PWM control
Use a 10 V PWM signal at 100 Hz-3 kHz. The plotted duty-cycle range is 10-100%, corresponding to 10-100% output current.
Resistance control
The plotted range is 10 kΩ/N to 100 kΩ/N for 10-100% current, where N is the number of drivers operated synchronously. For one driver this is 10-100 kΩ.
Wiring and isolation
DIM+ is purple; DIM- is pink. Do not connect DIM- to -V. The installation manual states that LPF dimming circuitry is not isolated from the secondary output; use a compatible controller.
Zero-brightness switching
Do not treat the 10% dimming endpoint as OFF. For 0% brightness, the catalog uses an external switch and relay to turn the lighting fixture on/off, or directs the installer to MEAN WELL for other options.
Environment and thermal design
Parameter
Details
Case temperature
Tcase -40 to +70°C; maximum case temperature +70°C. These are case-temperature limits, not ambient ratings. Measure at the tc point shown in the mechanical drawing.
Ambient temperature and derating
Horizontal installation: ambient load curve shows 100% through +50°C, then a linear decrease to 60% at +70°C. Keep the case measurement point within the separate Tcase limit. The shaded low-temperature range from -40°C to -25°C is marked for 230 VAC input only in both the ambient and case-temperature graphs.
Cooling / orientation
Fanless, free-air convection. Mount in the horizontal direction shown in the mechanical drawing. Nonstandard orientation or elevated ambient temperature requires output-current derating.
Ingress protection
Fully encapsulated IP67 plastic housing; catalog suitability includes dry, damp and wet locations. Provide protected wiring and connections and follow the installation manual. Do not immerse or operate the driver in water.
Humidity / storage
Operating humidity: 20-95% RH, non-condensing. Storage: -40 to +80°C and 10-95% RH.
Altitude
For this fanless driver, reduce the ambient-temperature limit by 3.5°C per 1000 m above 2000 m altitude.
Temperature coefficient / vibration
±0.03%/°C over 0-50°C. Vibration: 10-500 Hz, 5 G; 12 min/cycle, 72 min on each X, Y and Z axis.
Dimensions, wiring and installation
Parameter
Details
Dimensions / mounting
161 x 61 x 36 mm (L x W x H), drawing tolerance ±1 mm. Two Ø4.5 mm mounting features; locate the hardware from the model drawing.
Input cable
SJOW 17 AWG x 2 conductors and H05RN-F 2 x 1.0 mm²; 300 ±20 mm. Brown = AC/L, blue = AC/N.
Output cable
Style 2464: 18 AWG x 4 conductors; 300 ±20 mm. Red = +V, black = -V, purple = DIM+, pink = DIM-.
Insulation / grounding
Class II plastic housing with no FG lead shown. Class II insulation and Class 2 power-unit classification are different characteristics.
Installation clearances
Disconnect the utility before installation or maintenance and prevent unintended reconnection. Keep ventilation clear and do not stack objects on the unit. Maintain 10-15 cm clearance when an adjacent device is a heat source.
Cable and system protection
Use approved primary and secondary cables rated at least for the driver current. Provide system-level insulation/isolation around interconnections, and enclose single-insulated wires. Where waterproof connectors are used, ensure a tight linkage that prevents water entering the system.
ErP installation condition
To meet the datasheet condition for the latest lighting-fixture ErP requirements, use this driver behind a switch; do not keep it permanently connected to the mains.
BSMI integration condition
For BSMI certification when connecting peripheral equipment, the LED installation manual requires LPF series to be installed with a fireproof enclosure rated V1 or higher.
Servicing
Do not remove the case yourself. Faults must be examined by a qualified technician. Damaged external flexible cable must be replaced by the manufacturer, its service agent or a similarly qualified person.
External control items
Select a compatible dimming controller and, when full OFF is required, the switch/relay arrangement in the catalog. These are system-level connection items; the diagram does not identify a supplied accessory set or dedicated order codes.
