AC phase-cut dimming
Use a compatible leading-edge or trailing-edge AC phase-cut dimmer on the mains input before the driver. The catalog specifies a conduction-angle range of 30° minimum to 180° maximum; these angles are not a guaranteed output-current or brightness percentage. The drawing provides AC/L and AC/N input leads and V+/V− LED output leads, with no separate dimming-control wires.
The following third-party dimmers are catalog compatibility examples at the stated supply voltage and frequency. Confirm the actual dimmer revision, load limits and permitted driver count with the dimmer manufacturer; listing does not mean the dimmer is supplied with this driver.

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

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

Reliability reference
Catalog minimum MTBF estimates: 4038.1 / 362.3 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.
Typical figures and performance curves depend on the specified input, load and operating conditions. Apply the model’s published ratings and installation instructions to the complete luminaire.
