Output and selection

Parameter	Specification
Model and code	PLD-40-1050B — PLD-40; 1050 denotes the rated output current in mA. B input version: 180–295 VAC.
Output mode	Constant-current LED driver with built-in active power factor correction (PFC). Non-dimmable constant-current operation.
Rated output current	1050 mA; current accuracy ±5.0%
Constant-current voltage range	22–38 VDC. Select a directly connected LED string whose total forward voltage stays inside this working window.
Rated output power	39.9 W
Maximum no-load voltage	50 V; this is not a rated LED operating voltage.
Maximum ripple and noise	2.6 Vp-p; 20 MHz bandwidth, measured with a 12-inch twisted pair terminated with parallel 0.1 μF and 47 μF capacitors.

Input and electrical performance

Parameter	Specification
Input voltage	180–295 VAC; B input version.
Input frequency	47–63 Hz
Typical efficiency	87%; model-specific specification-table value, dependent on actual load and input conditions.
Typical power factor	>0.9 at 230 or 277 VAC at full load; see the catalog load curves.
THD	<20% at ≥60% load / 230 VAC, or ≥75% / 277 VAC.
Typical AC input current	0.35 A at 230 VAC; 0.3 A at 277 VAC
Setup time	500 ms at 230 VAC at full load.
Inrush current	Cold start: 25 A typical at 230 VAC; 60 μs width at 50% peak.
Circuit-breaker reference	47 / 47 units on type B / type C 16 A breakers at 230 VAC, respectively. These are breaker types, not product suffixes; verify the actual breaker and installation.
Leakage current	<0.5 mA at 240 VAC

Protection and operating conditions

Parameter	Specification
Short-circuit protection	Hiccup mode with automatic recovery after the fault is removed.
Overtemperature protection	Output shuts down and recovers automatically after temperature returns to a safe level.
Ambient temperature	−30 to +50°C, subject to the load curve.
Cooling and load derating	Free-air convection; horizontal mounting as specified by the catalog curve. 100% load through +50°C; the operating curve ends at +50°C. Derate for nonstandard mounting and apply all input and thermal limits together.
Input/load curve	100% load across 180–295 VAC within the applicable thermal limits.
Humidity and storage	Working: 20–95% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH.
Temperature coefficient	±0.03%/°C over 0–50°C
Altitude derating	Above 2000 m, reduce allowable ambient temperature by 3.5°C per additional 1000 m for this fanless design.
Vibration	10–500 Hz, 2 G, 12 minutes per cycle, 72 minutes along each X/Y/Z axis.

Safety and EMC

Parameter	Specification
Safety and enclosure	Class II fully isolated plastic housing without an FG connection; IP42 enclosure. ENEC BS EN/EN61347-1 and BS EN/EN61347-2-13 independent control gear; BS EN/EN62384; EAC TP TC 004. BIS IS15885 (Part 2/Sec 13) applies to this listed model. CCC is shown as optional; verify the supplied unit’s markings for the intended market.
Withstand voltage	Input-to-output: 3.75 kVAC
Insulation resistance	Input-to-output: 100 MΩ at 500 VDC, 25°C and 70% RH
EMC emissions	BS EN/EN55015; BS EN/EN61000-3-2 Class C; BS EN/EN61000-3-3; EAC TP TC 020.
EMC immunity	BS EN/EN61000-4-2, -3, -4, -5, -6, -8 and -11; BS EN/EN61547 for the light-industry level; surge 2 kV, criterion B; EAC TP TC 020. Recheck EMC in the complete installation.

Dimensions, wiring and installation

Parameter	Specification
Body dimensions	128 × 60 × 31.5 mm (L × W × H)
Mounting	Two Ø3.8 mm mounting holes; case PCD40A. Body length 128 mm, total flange length 143.9 mm and longitudinal hole spacing 134.5 mm. Drawing tolerance ±1 mm. Recommended assembly/mounting-screw torque: 3.2–4.8 kgf·cm per the LED installation manual; this is not a wire-terminal torque.
AC input leads	H03VVH2-F 0.75 mm² × 2C; brown AC/L and blue AC/N. Lead length 75 ±5 mm.
LED output leads	UL1430 18 AWG; red V+ and black V−. Lead length 150 ±10 mm. Check polarity before connection.
Installation	Disconnect the supply before installation or maintenance and prevent accidental reconnection. Keep ventilation clear and do not stack objects on the driver. Leave 10–15 cm clearance when an adjacent device is a heat source. Insulate all system interconnections and cover single-insulated wiring with the system enclosure. Use suitable cable current ratings; route and secure the leads without strain. Do not immerse the unit or expose it to excessive heat or fire. Do not open the case; damaged external wiring must be replaced by the manufacturer, its service agent or an equally qualified person.
LED connection and mains switching	Connect LEDs directly to the output; this driver is not suitable for use with additional drivers. The LED string’s total forward voltage determines the operating output voltage within the specified constant-current range. Keep current and power within the rating. For the stated ErP application, install the driver behind a switch rather than permanently connected to the mains.
Catalog mass	220 g per unit, from PACKING 0.22 kg. Catalog packing reference, not a measured net or shipping weight.
Reliability reference	Catalog minimum MTBF estimates: 4826.5 / 865.2 thousand hours for Telcordia SR-332 / MIL-HDBK-217F (25°C), respectively; not a service-life guarantee.
Manufacturer warranty	Catalog states a 3-year warranty, subject to the manufacturer’s warranty statement and applicable conditions.
