Dimmer, 2 outputs Type G 3448 5234 Du line® Fieldbus Installationbus • Switching and dimming of lamps • 8 control-channel receiver • Negative or positive phase angle dimming • For DIN-rail mounting • LED-indications for Alarm, Dupline® carrier and outputs • Lamp-protective soft-start function • Channel coding by GAP 1605 • 4 lighting scenes • Transmits the status of the dimming outputs • Protected against short-circuit and overload Product Description Ordering Key G 3448 5234 230 The G3448 5234 2-output lighting scene dimmer is a component of the Dupline Installation System. It permits different types of lamps with wattages up to 2 x 230 W to be operated and dimmed and enables up to 4 lighting arrangements (per output) to be stored, which can then be retrieved at any time. In addi- tion, it transmits the status of push-button combinations or by means of the test unit, the lighting scenes can be unlocked, modified and also retrieved. With the change- over switches on the front panel, it is possible to select either negative phase angle control or positive phase angle control dimming. The lighting is switched on via a bulb-conserving softstart Type: Dupline® "H4"- Housing Dimmer 8 Channels 2 outputs MOSFET 2 x 230 W Analog Power supply Type Selection Supply Ordering no. the dimming output for every facility. The dimmer is elec- individual output. The dimmer setting which was selected last is stored as a "memory setting" in the internal memo- ry and is reselected next time the lighting is switched on via channel 1/5. A power failure will erase the memory setting. The brightness of the lighting scenes is preset at the factory in steps these settings can- not be altered. By the aid of tronically protected at the power output against over- load and short circuits. The "Fault" LED on the front indi- cates both faults by means of different flashing frequencies. An alarm caused by an over- load or short circuit must be reset manually after rectifying the fault by disconnecting the phase from the mains supply for approx. 3 seconds. 230 VAC G 3448 5234 230 Supply Specifications Power Supply Rated operational voltage 230 VAC ±10% Power consumption 12 VA Power dissipation Max. 3.5 W Frequency 50/60 Hz Output Specifications Outputs 2 Dimming capacity 2 x 230 W Rated operational voltage 230 VAC ±10% Dimming speed 3.6 s (5% - 100%) Response time 1 Cycle: ≤ 272 ms @ 128 channels) General Specifications Power ON delay 7 s Indication for Supply On LED, Green Alarm LED, Red – Flashing Slow flashing: Overload Fast flashing: Short circuit Dupline® carrier LED, Yellow Output On LED, Red (one per output) Environment Operating temperature 0° to +50°C/32° to +122°F Humidity (non-condensing) Max. 85% Housing H4-housing Operating Device Switch for selection of ne- gative/positive phase angle control for each individual dimmer Standards IEC 60669, EN 55022/ EN 50081-1 and EN 55024/ EN 50082-1 Specifications are subject to change without notice (07.05.2007) 1 Dupline® is a registered trademark.
