Clipsal by Schneider Electric | 30 Series Rotary Dimmer Mechanism 350W Trailing Edge | White
The Clipsal 30ERDM-WE is a rotary dimmer mechanism rated 350 W, supplied in White. Push the knob to switch the circuit, then turn it to set the level. The 30ERDM-WE is a 2 wire trailing edge phase control dimmer running on 220 to 240 V AC, 50 Hz.
The 350 W rating applies to a single dimmer on the plate. A derate applies once dimmers are ganged on one plate. Two per plate drops the LED load to 300 W, three to 250 W, four to 195 W, five to 140 W and six to 90 W. The bottom end matters too, with a minimum load of 3 W below which the dimmer sits outside its rating.
Dimming is trailing edge phase control on a 2 wire configuration, wired for one-way or two-way switching. The mechanism carries short circuit and thermal overload protection. It is listed to AS/NZS 60669.2.1 and AS/NZS CISPR-15, and clips into the grid plate.
Features
- Trailing edge phase control — the 30ERDM-WE dims by trailing edge, which is the technique published for this mechanism.
- Rotary push type control — push the knob to switch the circuit, turn clockwise to brighten and counter-clockwise to dim.
- 350 W maximum load — a single dimmer on the plate carries up to 350 W.
- 3 W minimum load — the circuit needs at least 3 W on it for the dimmer to be within rating.
- Published gang derate — LED capacity falls to 300 W at two per plate and down to 90 W at six.
- Three load types — rated for LED, incandescent lamp and electronic transformer loads.
- 2 wire configuration — the 30ERDM-WE wires as a 2 wire device with no neutral at the mechanism.
- One-way and two-way — wiring diagrams cover both one-way and two-way dimming and switching.
- Adjustable minimum brightness — the knob and adapter come off so the bottom of the dimming range can be set on site.
- Short circuit and overload protection — short circuit protection and thermal overload protection are both published.
- AS/NZS 60669.2.1 listed — compliance covers AS/NZS 60669.2.1 and AS/NZS CISPR-15.
- IP20 rated — protection covers solid objects only, and the 30ERDM-WE carries no rating against water ingress.
Where to use
- Dimmable LED lighting — the 30ERDM-WE is rated for LED, incandescent and electronic transformer loads on one mechanism.
- Two-way dimming positions — the published wiring covers two-way dimming and switching as well as one-way.
- Multi-gang dimmer plates — ganging is allowed provided the load is cut to the published figure for that gang count.
- Grid plate installations — the 30ERDM-WE clips into the grid plate rather than fixing with screws.
- Indoor positions to 40 degrees C — the 30ERDM-WE has a published operating range of 0 to 40 degrees C.
The 30ERDM-WE is rated IP20, which covers solid objects only and gives no rating against water. It is not suitable for outdoor or damp positions such as bathrooms, laundries and external walls. Loads below 3 W or above 350 W sit outside the rating, and the ganged figures cut that ceiling further.
