Model, output and control

Parameter	Specification
Model	SPWM-75-24
Series and function code	SPWM-75; blank suffix: 3-in-1 dimming
Output mode	Constant voltage with PWM-style output; dimming varies output-current duty cycle. Built-in active power factor correction (PFC).
DC output voltage	24 V
Rated output current	3.2 A maximum
Rated output power	76.8 W maximum
Voltage adjustment range	23–26 V via +V ADJ; keep the load within rated current and power.
Output PWM frequency	3.2 kHz, fixed typical output waveform frequency.
Dimming interface	0–10 VDC, additive 10 V PWM at 300 Hz–3 kHz, or 0–100 kΩ resistance between DIM+ and DIM−
Dimming range	Approximate minimum 6%; output current is undefined between 0% and 6%. Dim-to-off is available at about 0 VDC, 0 kΩ or 0% duty of the external 10 V PWM signal.
Dimming source and synchronization	100 μA typical source current. Resistance scaling: 100 kΩ / N at full output, where N is the number of synchronized drivers. Do not connect DIM− to the negative LED output. Connect LEDs directly; use with additional drivers is not recommended.

Input and performance

Parameter	Specification
Input voltage	100–305 VAC or 156–410 VDC; apply input-voltage and thermal derating. Before DC wiring, verify the manufacturer’s polarity requirements for this model.
Input frequency	47–63 Hz
Typical efficiency	90% at the catalog test conditions
Typical power factor	>0.97 / 115 VAC; >0.95 / 230 VAC; >0.92 / 277 VAC at full load; PF changes with load.
THD	<10% at ≥50% load / 115 or 230 VAC, or ≥75% / 277 VAC; consult the model-specific load curves.
Typical AC input current	0.9 A / 115 VAC; 0.45 A / 230 VAC; 0.38 A / 277 VAC
Inrush current	Cold start: 50 A typical at 230 VAC; 500 μs pulse width measured at 50% peak, per NEMA 410.
Circuit-breaker reference	5 / 8 units for type B / type C 16 A breakers at 230 VAC, respectively. Catalog reference only; verify the actual breaker and system conditions.
Leakage current	<0.25 mA at 277 VAC
No-load or standby power	<0.5 W with dimming off.
Setup and rise time	500 ms setup, 80 ms rise / 230 VAC; 1200 ms setup, 80 ms rise / 115 VAC. Cold-start measurement; rapid switching may increase setup time.
Hold-up time	10 ms / 230 VAC or 115 VAC typical

Protection and operating conditions

Parameter	Specification
Overload protection	105–135% of rated output; Hiccup mode; automatic recovery after the fault is removed.
Short-circuit protection	Output shuts down; remove the fault, then re-power to recover.
Overvoltage protection	27–36 V; Output shuts down; remove the fault, then re-power to recover.
Overtemperature protection	Output shuts down; remove the fault, then re-power to recover.
Working case temperature	−20 to +90°C; maximum case temperature +90°C, subject to derating.
Cooling and load derating	Free-air convection, vertical mounting, as specified by the catalog curves. At 110 VAC: 100% load through +40°C, falling to 60% at +60°C. At 230 VAC: 100% through +50°C, falling to 60% at +60°C. Keep measured Tc at or below +90°C; the case-temperature limit does not replace the ambient curve.
Input/load derating	At 60 Hz, vertical mounting: 90% at 100 VAC, rising to 100% at 110 VAC; 100% through 305 VAC.
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 the allowable ambient temperature by 3.5°C per additional 1000 m for this fanless design.
Vibration	5–100 Hz, 2 G, 12 minutes per cycle, 72 minutes along each X/Y/Z axis.

Safety, insulation and compliance

Parameter	Specification
Safety and design standards	UL8750 Class P; CSA C22.2 No. 250.13-12; ENEC BS EN/EN61347-1 and BS EN/EN61347-2-13; Class II plastic housing without FG and SELV output. BS EN/EN62384, GB/T19510.1, GB/T19510.213 and EAC TP TC 004; AS/NZS61347-1/-2-13 are design references. RCM is voluntary; the catalog identifies Non-IC independent LED control gear as unsuitable for residential installations under that classification.
EMC	Emission: BS EN/EN55015 (CISPR15), GB/T17743; BS EN/EN61000-3-2 / GB17625.1 Class C at ≥50% load; BS EN/EN61000-3-3. Immunity: BS EN/EN61547; BS EN/EN61000-4-2 ESD 8 kV air / 4 kV contact; -4-3/-4-4/-4-6/-4-8 level 2; -4-5 line-to-line 2 kV (level 4); -4-11:2020 30% dip for 10 periods and 100% interruption for 0.5 periods. Final equipment requires EMC requalification.

Dimensions and installation

Parameter	Specification
Dimensions	290 × 38 × 28.5 mm (L × W × H); slim plastic terminal-block housing.
Terminal connections	TB1: 1 AC/L, 2 AC/N. TB2: 1 +V, 2 +V, 3 −V, 4 −V, 5 DIM+, 6 DIM−.
Terminal wire preparation	TB1/TB2: 0.75–2.50 mm² (18–14 AWG), 6–7 mm stripping length, M2.5 terminal screws; suggested tightening torque 0.4 N·m (3.5 lb·in).
Mounting	Use the model-specific drawing and 4.2 mm mounting features. Provide ≥15 cm spacing between drivers and do not stack them. The SPWM manual requires a ≥7 mm shim below the fixing screws to leave a heat-dissipation gap.
Installation	Qualified personnel only. Disconnect power before wiring or maintenance; verify secure, correct wiring before energizing. Do not open the case. Do not install in damp locations, excessive heat, direct sunlight or near fire. Close and secure the protective terminal covers. Capacitive loads are not recommended.
Weight	310 g; catalog packing reference per unit (0.31 kg × 1000), not a measured net or shipping parcel weight.
Service-life reference	Typical lifetime >50,000 hours when the marked Tc/TMP point is about +75°C or below. Manufacturer catalog warranty: 5 years, subject to MEAN WELL’s warranty statement; not an additional store promise.

Unless stated otherwise, catalog parameters are measured at 230 VAC input, rated current and +25°C ambient. Typical figures and load curves apply only to their stated conditions. Read the linked drawings and installation instructions before system design.
