Protection and operating conditions
Parameter
Specification
Overload protection
105–150% of rated output; Hiccup mode; automatic recovery after the fault is removed.
Short-circuit protection
Hiccup mode; automatic recovery after the fault is removed.
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 +80°C; maximum case temperature +80°C, subject to derating.
Cooling and load derating
Free-air convection, vertical mounting, as specified by the catalog curves. At 110 VAC: 90% load through +40°C, falling to 60% at +50°C. At 230 VAC: 100% through +45°C, falling to 60% at +50°C. Keep measured Tc at or below +80°C; the case-temperature limit does not replace the ambient curve.
Input/load derating
At 60 Hz, vertical mounting: 80% at 100 VAC, rising to 90% at 110 VAC; the 90% plateau continues below 200 VAC, with a step to 100% at 200 VAC through 305 VAC. Below 110 VAC at −20°C, a restart may occur within 5 seconds after power-on.
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.
Control wiring and operation
Parameter
Specification
DALI/PUSH connection
Use the DALI pair for DALI control. For primary-side PUSH, follow the dedicated wiring diagram: connect TB1 pin 5 (DA−/N) to neutral and a push button between line and pin 4 (DA+/L); PUSH2 uses a second button between line and pin 3 (PUSH/L).
PUSH timing and limits
Factory brightness 100%. Short press: 0.1–1 second; long press: >1 second. One common push button supports up to 10 drivers; maximum cable length to the last driver is 20 m.
PUSH brightness
Short press switches on/off. Long press dims up/down and stops at maximum or minimum dim (not dim-off); each next push reverses direction. Brightening from off is possible. Responses depend on the DIP mode below.
DIP 1/2/3: ON / ON / ON
1 DT6 logical gear / 1 DALI address; use CH1 for the LED load. PUSH1 controls brightness; PUSH2 has no response.
DIP 1/2/3: ON / ON / OFF
4 DT6 logical gears / 4 addresses; CH1–CH4 are separate brightness channels. PUSH1 controls all four synchronously; PUSH2 has no response.
DIP 1/2/3: OFF / OFF / OFF
Factory default RGBW DT8: 1 logical gear / 1 address. CH1 red, CH2 green, CH3 blue, CH4 white. PUSH1 controls brightness. PUSH2 short press selects white or RGB control; long press adjusts white (minimum 0) or changes RGB colour.
DIP 1/2/3: ON / OFF / OFF
1 tunable-white Tc DT8 logical gear / 1 address: CH1 cool white + CH2 warm white; CH3/CH4 unused. PUSH1 controls brightness; PUSH2 short press switches on/off and long press performs Dim2Warm.
DIP 1/2/3: OFF / ON / OFF
2 tunable-white Tc DT8 logical gears / 2 addresses: CH1 cool + CH2 warm, CH3 cool + CH4 warm. PUSH1 synchronizes brightness of both gears; PUSH2 synchronizes Dim2Warm and on/off.
DIP 1/2/3: OFF / OFF / ON
Mixed DT6 + tunable-white DT8: 2 logical gears / 2 addresses. CH3 is DT6; CH1 cool + CH2 warm form DT8, CH4 unused. PUSH1 responds only for DT6; PUSH2 responds only for DT8.
Dim2Warm behavior
Dimming down warms colour temperature; dimming up cools it. Long press stops at minimum dim, not dim-off; next push reverses direction. Operation from off is possible.
RGBW duty and load limits
Normalized colour control (factory default): a+b+c+d ≤100%. Extended colour control, enabled by DALI commands: sum ≤400%. In either mode, instantaneous total output power of all four channels must not exceed 151.2 W. The duty sum does not multiply the product power rating; size all connected channels for the shared 6.3 A total rating.

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.

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.
