Output and load selection

Output mode Single-output constant-current design.
Constant-current operating region 42–72 V DC. Use this model-specific region for LED load selection.
Rated output current 0.35 A (350 mA).
Rated output power 25.2 W.
No-load output voltage 80 V maximum.
Ripple and noise 7.2 Vp-p maximum. Measured with 20 MHz bandwidth and a 12-inch twisted-pair lead terminated with 0.1 µF and 47 µF capacitors in parallel.

Setup time 500 ms at 115 VAC or 230 VAC, at full load.
Load application Indoor LED lighting, including office, commercial and decorative lighting. Direct connection to LEDs is suggested; the supply is not suitable for use with additional drivers. Confirm any special electrical requirements of the final system.
Constant-current selection note The datasheet describes the constant-current region generally as 60–100% of rated output voltage; use the explicit model-specific operating region above when selecting the LED string.

Construction, terminals and dimensions

Construction Fully isolated plastic case, with UL 94V-0-rated flame-retardant material and screwless clamp-style terminal-block input and output.
Dimensions 145 × 38 × 22 mm (L × W × H). Mechanical drawing: Case No. PLM-25; general tolerance ±1 mm.
Mounting drawing The two diagonal open mounting features are marked Ø3.5 mm, with 4.5 mm edge-position references. The side view also marks a 3.5 mm local base/flange dimension; follow the dimensioned drawing for installation.
Case-temperature measurement point The marked Tc point is 65 mm from the right-hand end and 12 mm from the lower edge in the plan view. These are location dimensions, not temperature ratings.
AC input terminal block TB1: SWITCHLAB MWX201-75002EB (gray). Pin 1 = AC/L; pin 2 = AC/N.
DC output terminal block TB2: SWITCHLAB MWX201-75002B (blue). Pin 1 = +V; pin 2 = −V.
Recommended wiring The mechanical drawing suggests UL1015 18 AWG × 2-core wire for both the input and output connections.
Accessory scope The series datasheet specifies the terminal blocks and recommended wiring, but gives no separate MEAN WELL accessory ordering code. The recommended wire specification is not a claim that cables are included.
Packing and weight 126 g (0.126 kg), catalog packing reference per unit; not a measured net-weight claim. Outer packing: 60 pieces, 8.6 kg, 0.48 CUFT.
General test conditions Unless otherwise specified, parameters are measured at 230 VAC input, rated load and 25°C ambient temperature.

Installation and system guidance

Installation isolation and service Disconnect the supply from the mains before installation or maintenance and prevent unintended reconnection. Have faults examined by a qualified technician; do not open the case yourself. Dispose of the LED supply together with the lighting equipment at end of life.
Ventilation and mechanical support Keep ventilation clear and do not stack objects on the unit. Maintain 10–15 cm clearance when an adjacent device is a heat source. Follow this model’s mounting orientation and derating diagrams. Check the mounting surface and luminaire structural strength; use safety cables for bay lighting applications. Do not immerse the unit in water.
Wiring and system enclosure Use approved input and output wiring with current ratings at least equal to the applicable unit current. Follow this model’s terminal assignments. This Class II ungrounded power supply has no FG terminal. Provide insulation around system interconnections and enclose single-insulated wiring. Keep output current and power within the model ratings and temperature limits. Have damaged external flexible cables replaced by the manufacturer, its service agent or similarly qualified personnel.
Circuit-breaker reference At 230 V AC, the installation manual gives calculated maximum quantities for PLM-25 with ABB S200-series breakers: B10 50, B16 80, C10 50, C16 80, D10 50 and D16 80. B, C and D identify breaker trip curves; 10 and 16 identify ampere ratings. These counts apply to that stated breaker and voltage reference.
EMC integration Reverify EMC in the finished equipment with the connected load and actual wiring and assembly. The linked guidance describes representative component-power-supply tests; its illustrated distances are test arrangements, not installation clearances.
