Output and selection

Parameter	Specification
Model and code	PLD-25-350 — PLD-25; 350 denotes the rated output current in mA. Universal AC input with the DC input range specified below.
Output mode	Constant-current LED driver with built-in active power factor correction (PFC). Non-dimmable constant-current operation.
Rated output current	350 mA; current accuracy ±5.0%
Constant-current voltage range	40–58 VDC. Select a directly connected LED string whose total forward voltage stays inside this working window.
Rated output power	20.3 W
Maximum no-load voltage	60 V; this is not a rated LED operating voltage.
Maximum ripple and noise	4.6 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	90–295 VAC or 127–417 VDC. For DC wiring, verify the manufacturer’s polarity instructions for the supplied model before connection.
Input frequency	47–63 Hz
Typical efficiency	85%; model-specific specification-table value, dependent on actual load and input conditions.
Typical power factor	>0.98 at 115 VAC; >0.92 at 230 VAC; >0.91 at 277 VAC at full load; see the catalog load curves.
THD	<20% at ≥70% load / 115 or 230 VAC, or ≥80% / 277 VAC.
Typical AC input current	0.6 A at 115 VAC; 0.3 A at 230 VAC; 0.2 A at 277 VAC
Setup time	500 ms at 230 VAC; 2000 ms at 115 VAC at full load.
Inrush current	Cold start: 25 A typical at 230 VAC; 75 μs width at 50% peak.
Circuit-breaker reference	72 / 80 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; remove the overtemperature condition and re-power to recover.
Ambient temperature	−30 to +60°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, falling to 50% at +60°C. Derate for nonstandard mounting and apply all input and thermal limits together.
Input/load curve	At 50/60 Hz: 100% load across 90–295 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. Class 2 power unit. UL8750; CSA C22.2 No. 250.0-08; ENEC BS EN/EN61347-1 and BS EN/EN61347-2-13 independent control gear; BS EN/EN62384; EAC TP TC 004. UL60950-1 is a design reference. CCC is shown as optional; verify the supplied unit’s markings for the intended market. The catalog lists dry/damp-location suitability, subject to the installation instructions and IP42 protection.
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; FCC Part 18 non-consumer; BS EN/EN61000-3-2 Class C (catalog condition: ≤75% load); 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/EN55024; BS EN/EN61547 for the light-industry level; EAC TP TC 020. Recheck EMC in the complete installation.

Dimensions, wiring and installation

Parameter	Specification
Body dimensions	84 × 57 × 29.5 mm (L × W × H)
Mounting	Two Ø3.6 mm mounting holes; follow case PCD16A drawing. 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	NISPT-1 18 AWG; black AC/L and white 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	190 g per unit, from PACKING 0.19 kg. Catalog packing reference, not a measured net or shipping weight.
Reliability reference	Catalog minimum MTBF estimates: 5524.2 / 968.2 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.
