Output and selection

Parameter	Specification
Identity and model code	SLD-80-12: SLD family, 80 W class, 12 V model code. Constant-voltage plus constant-current mode. The family wattage label is not a substitute for the exact rating.
Rated output power	79.2 W; input-voltage and thermal derating apply.
Rated output current	6.6 A.
Output voltage region	8.4–12 V in constant-current operation. Nominal constant-voltage output: 12 VDC.
Ripple and noise	150 mVp-p maximum. Measured with 20 MHz bandwidth using a 12-inch twisted pair terminated by parallel 0.1 μF and 47 μF capacitors.
Voltage tolerance and regulation	±4.0% voltage tolerance, including setup, line and load regulation. Line regulation ±0.5%; load regulation ±1.5%.
Startup and hold-up	Setup 500 ms, rise 80 ms at 115 / 230 VAC. Typical hold-up 10 ms at 230 VAC and 115 VAC. Setup is measured at first cold start; repeated ON/OFF can increase it.
LED driving mode	Constant-current mode can directly drive suitable LEDs; constant-voltage mode is normally used with an appropriate downstream DC/DC LED driver. In the constant-current region, the highest output voltage depends on the end-system configuration; confirm compatibility. The diagram separates constant voltage, constant current and hiccup protection regions.
Typical efficiency	90.5% at the catalog test condition. Unless stated otherwise, specifications use 230 VAC input, rated current and 25°C ambient. The performance plots identify a 24 V model at Tcase 75°C.

Input supply

Parameter	Specification
Input supply	110–305 VAC; 155–431 VDC; 47–63 Hz AC. Built-in active PFC.
Power factor	PF ≥0.97 at 115 VAC; ≥0.95 at 230 VAC; ≥0.92 at 277 VAC, at full load.
Total harmonic distortion	THD <10% at load ≥60% / 115 or 230 VAC or load ≥75% / 277 VAC.
AC current	0.9 A / 115 VAC; 0.45 A / 230 VAC; 0.38 A / 277 VAC.
Typical inrush and circuit-breaker reference	50 A; width 270 μs at cold start, 230 VAC, width measured at 50% Ipeak, per NEMA 410. At 230 VAC on a 16 A circuit breaker: 8 type B / 16 type C units maximum in the catalog reference.
Leakage current	<0.25 mA at 277 VAC.
No-load power consumption	<0.5 W.

Protection and recovery

Parameter	Specification
Overcurrent	95–108%; constant-current limiting or hiccup mode; automatic recovery after the fault is removed.
Short circuit	Hiccup mode; automatic recovery after the fault is removed.
Overvoltage	14–17 V; output shuts down; reapply power to recover.
Overtemperature	Output shuts down; reapply power to recover.

Operating conditions

Parameter	Specification
Case temperature and cooling	Free-air convection. Operating Tcase −20 to +90°C; maximum Tcase +90°C. Case temperature and ambient temperature are different limits.
Ambient derating in horizontal mounting	At 110 VAC: 100% load from −20 to +40°C ambient; at 230 VAC: 100% through +50°C. Derate along the respective curves to 50% load at +65°C.
Input-voltage derating at 60 Hz	Rated operation is 110–305 VAC. The static plot shows full load at 110–305 VAC, decreasing below that boundary; the plotted 100 VAC point does not extend the specified input range.
Altitude derating	For this fanless driver above 2000 m (6500 ft), reduce allowable ambient temperature by 3.5°C per additional 1000 m.
Humidity and storage	Operating 20–95% RH, non-condensing. Storage −40 to +80°C.
Temperature coefficient	±0.03%/°C over 0–50°C.
Vibration	10–500 Hz, 2 G, 12 minutes/cycle; 72 minutes on each X, Y and Z axis.
MTBF	2666.8 / 260.9 thousand hours minimum: Telcordia SR-332 / MIL-HDBK-217F at 25°C, respectively.
Service life and warranty	Typical life expectancy 30,000 hours when the designated tc/TMP point is about 75°C or lower. The graph shows life decreasing as case temperature increases; it is not a guaranteed replacement interval. Manufacturer warranty 3 years, subject to applicable manufacturer terms.

Safety and installation qualifications

Parameter	Specification
Construction and classification	Plastic slim linear housing, Class II design. The catalog explicitly excludes the 12 V model from its Class 2 feature; do not treat this as a Class 2 unit.
Safety standards	UL8750; CSA C22.2 No.250.13-12; ENEC BS EN/EN61347-1 and -2-13 independent; BS EN/EN62384; EAC TP TC 004; GB/T19510.1 and GB/T19510.213; IS15885 (Part 2/Sec 13); EN60335-1, as listed in the dedicated specification.
Electrical insulation	Input–output withstand 3.75 kVAC. Input–output insulation resistance 100 MΩ at 500 VDC, 25°C and 70% RH.
EMC emissions	Conducted and radiated: BS EN/EN55015 (CISPR15); GB/T17743; EN IEC55014-1 (CISPR14-1). Harmonic current: BS EN/EN61000-3-2 and GB17625.1, Class C at load ≥60%. Voltage flicker: BS EN/EN61000-3-3.
EMC immunity	BS EN/EN61547 and EN IEC55014-2. ESD: Level 3, 8 kV air; Level 2, 4 kV contact. Radiated, EFT/burst, conducted and magnetic-field tests: Level 2. Surge: 1 kV line-to-line. Applicable test series: BS EN/EN61000-4-2, -3, -4, -5, -6, -8 and -11.

Complete-installation responsibility	This driver is a component of the final equipment; requalify EMC on the complete installation. Catalog RCM/Non-IC independent-controlgear note states it is unsuitable for residential installations and recommends commercial decoration, signage or luminaire applications. Apply that installation qualification rather than treating a general application example as approval.

Dimensions, connection and installation

Parameter	Specification
Dimensions and mounting	320 × 30 × 16.8 mm (L × W × H); drawing tolerance ±1 mm. Two Ø3.5 mm mounting holes; the drawing gives 312 × 22 mm mounting-reference dimensions. Use the complete drawing for placement.
Designated case measuring point	The top-view tc point is located by 124 mm and 15 mm reference dimensions in the drawing. Measure the designated point in the final installation.
Input terminals	TB1: pin 1 AC/L, pin 2 AC/N. DEGSON DG219-3.5 gray terminal.
Output terminals	TB2: pin 1 +V, pin 2 −V. DEGSON DG219-3.5 red/black terminal.
Wiring dimensions	Input and output conductor area 0.75–1.50 mm²; strip length 9–10 mm, per the mechanical drawing.
Adjustment and ordering scope	This exact 12/24 V model is specified for CV/CC operation; no B/DA external-dimming suffix or separate accessory is defined in its model code.
Unit weight reference	206 g, converted from the explicit single-unit PACKING mass. This is the catalog packing reference, not a measured net or shipping weight.
Carton reference	64 units / 14.184 kg / 0.75 cu.ft. The unit weight is not calculated by dividing the carton mass.
Installation safety	Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself.
Ventilation and mounting	Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements.
System wiring and protection	Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system. Connect a fitted FG terminal to protective earth; the manual exempts only units marked Class II and ungrounded.
Environmental and load limits	Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person.
Installation-manual breaker reference	The installation-manual reference table gives 8 units on B16 and 16 on C16 for SLD-50/80, based on ABB S200 calculations; confirm the actual breaker and installation.
