DLC-02 controller: combined catalog pages 7–13. Product-sheet date: 2024-10-16. Bus-current and relay-contact ratings are separate limits.

Electrical ratings and protection

Parameter	Details
Input range	100–305 VAC, 47–63 Hz, or 140–430 VDC; Class II construction. The catalog does not specify a DC polarity assignment for L/N; confirm the manufacturer’s DC connection instructions before DC use.
DALI bus power	Two built-in 16 V bus power supplies. Guaranteed supply current: 240 mA per bus; maximum supply current: 250 mA per bus. Total rated output power: 7.68 W.
AC current	0.5 A typical at 115 VAC; 0.25 A typical at 230 VAC.
Setup and rise time	250 ms setup and 50 ms rise at 115 VAC and 230 VAC.
Inrush current	Cold start: 45 A typical at 230 VAC.
Short-circuit protection	0.7 s short-circuit delay to shutdown; 5 s restart period and 0.7 s retry time.
Relay outputs	Four independent relay channels. Each contact is rated 10 A at 125 VAC or 5 A at 250 VAC. Do not extend the relay voltage rating to the controller’s 305 VAC input limit.

Control functions and connections

Parameter	Details
DALI channels	Two independent DALI channels, each supporting up to 64 control gears. Each channel provides 16 groups and 16 scenes.
Supported control gear	DT6 LED control gear (part 207) and DT8 color control (part 209), including tunable white, RGBW and xy color.
Configuration	Scan, address, group and configure the connected devices with MEAN WELL DLC-02 software. Ethernet control uses Modbus TCP/IP through the RJ45 connector.
Sequences and timers	The 2024-10-16 product sheet lists up to 255 timer events and 8 sequences with up to 16 steps each. The linked manual for firmware above version 3.0 lists 16 sequences of 16 steps. Confirm the supported capacity for the installed firmware; input-device events can trigger configured lighting effects.
Clock retention	Built-in battery retains the real-time clock during loss of AC power; synchronize the clock as described in the configuration procedure.
Local controls	OLED display and three front buttons: MOVE, SET and ESC. Two bus-voltage LEDs, four relay LEDs and one power LED show operating status.
USB	One USB slave connector, type B.
DALI input devices	Up to 12 input devices per channel, subject to the total bus-current budget. Supported input-device types include push buttons (part 301), absolute inputs/sliders (part 302), occupancy sensors (part 303) and light sensors (part 304).
Bus-current design	Use the 240 mA guaranteed current per channel as the operating budget. The catalog’s 12-device illustration instead calculates from the 250 mA maximum supply current; do not treat that maximum illustration as an unconditional guaranteed-current allowance.

Mounting and environment

Parameter	Details
Dimensions and enclosure	144 × 90 × 58.3 mm (L × W × H); ABS-V0 enclosure, 8 modular units wide.
DIN-rail mounting	35 mm rail, TS35/7.5 or TS35/15 according to the mechanical drawing.
Operating temperature and derating	−25°C to +45°C. The vertical-mounting curve shows 100% load through +45°C and stops there; no higher-temperature full-load operation is specified.
Input/load curve	The static characteristic shows 100% load from 100 to 305 VAC at 60 Hz.
Operating humidity	5–93% RH, non-condensing; climatic reference EN 50090-2-2.
Storage conditions	−25°C to +70°C; 10–95% RH, non-condensing.
Altitude	Operation up to 2,000 m (6,500 ft).
Vibration	5–150 Hz, 2G, 12-minute cycle along each X, Y and Z axis; EN 50090-2-2.
Terminal wiring	Follow the marked L/N supply, K1–K4 relay contacts and separate bus A / bus B DALI terminals. Use the exact model’s diagram; the KNX and Ethernet interfaces are not interchangeable.
Screw-terminal installation	The product sheet specifies 1.0–2.5 mm² solid or finely stranded wire and a 2.5 × 0.4 to 3.5 × 0.6 mm slotted screwdriver. Confirm conductor acceptance for the supplied terminal revision; see the installation instructions below for the catalog/manual tightening-torque difference.
Unit mass	430 g per unit; packing reference: 30 pieces / 13.9 kg / 1.30 CUFT.

Standards and reliability

Parameter	Details
Safety standards	BS EN/EN 61347-1 and BS EN/EN 61347-2-11.
DALI compliance	DALI-2 control interface; the series specification explicitly lists BS EN/EN 62386-103. Use the manufacturer’s current DALI certification and supported-device documentation when commissioning.
EMC emissions	BS EN/EN 55015; harmonic current Class A.
EMC immunity	BS EN/EN 61547.
MTBF reference	618,900 hours minimum per Telcordia SR-332; 190,100 hours minimum per MIL-HDBK-217F at 25°C. These are calculated reliability references, not guaranteed service life.
Specification conditions	Unless stated otherwise, catalog parameters are measured at 230 VAC and 25°C ambient temperature.
Manufacturer warranty reference	The catalog states a 5-year manufacturer warranty, subject to its applicable terms.

Manufacturer installation instructions

Parameter	Details
Installation and servicing	Installation and fault diagnosis must be performed by a qualified technician. Do not open the case yourself or install the unit in high moisture, high ambient temperature or direct sunlight.
Mounting orientation	Mount on TS35/7.5 or TS35/15 DIN rail with the DALI terminals facing downward so that cooling is not obstructed. Engage the top edge, slide down and press the bottom into place, then check that the unit is locked.
Terminal torque discrepancy	The current catalogue states 0.8 Nm, while the supplementary manual recommends 5 kgf-cm (4.4 lb-in) for the screw terminals. These values differ. Confirm the installation instructions applicable to the supplied hardware revision with MEAN WELL before tightening.
DALI cable design	The manual permits up to 64 electronic control gears per DALI bus and a maximum 300 m cable length when using 1.5 mm2 conductors. Device addressing and the available bus-current budget must both be respected.
Manual and firmware scope	The March 2025 Version 4 installation manual states applicability to firmware above version 3.0. Match the PC software, firmware and configuration instructions to the supplied device before commissioning.
Conductor preparation	The manual specifies 7-8 mm stripping for AC, relay and DALI screw terminals and a 3 mm slotted screwdriver. Select conductors suitable for the actual terminal revision and load.
Configuration reset	Resetting the DLC-02 connection password to its factory default also clears the device parameters. Preserve the required configuration before resetting and recommission afterward.
