Power Supply Units
20 V AC Power Supply Unit
The power supply unit converts 230 V AC into 20 V AC and is thus suited for the operation of devices with a supply voltage of 20 V AC (e.g. for the 24 V DC (20 V AC) design models of KNX weather sensors).
Functions and Operation:
- Connection without screws by means of tension clamps
Technical Data:
| Mounting | Snap-on fitting on mounting rails |
| Protection category | IP 20 |
| Dimensions | approx. 53 × 90 × 50 (W × H × D, mm), 3 width units |
| Weight | approx. 210 g |
| Ambient temperature | Operation -40…+70°C, storage -55…+90°C |
| Ambient air humidity | max. 95% RH, avoid bedewing |
| Input voltage | 230 V AC, 50 Hz |
| Output voltage | 20 V AC |
| Power | 3.8 VA |
Scope of Delivery:
- 20 V AC Power Supply Unit
- Data sheet with instrallation instruction (English, German, French, Italian or Spanish)
WGDC-2S Power Supply Unit
For DC Motors
The Power Supply Unit WGDC-2S can be set to the output voltage of 12 volt, 24 volt, or to “softstart”. The “softstart” functionality makes the power supply unit particularly suitable for precise regulation of the slat angle of blinds because the switch in the output voltage of 12 volt to 24 volt occurs only after one second of operation.
Functions and Operation:
- Can be set to an output voltage of 12 V DC, 24 V DC or to „softstart“
- Integrated changeover relay
- Output current max. 2 A altogether, e. g. for parallel operation of four 500 mA DC motors
- Connection clamps are labelled and pluggable
Technical Data:
| Housing | Plastic material |
| Colour | Grey |
| Mounting | On-wall |
| Protection category | IP 54 |
| Dimensions | 160 × 80 × 57 (W × H × D, mm) |
| Weight | approx. 955 g |
| Ambient temperature | Operation -40…+70°C Storage -55…+90°C |
| Operating voltage | 230 V AC, 50 Hz |
| Outputs | 2 x Drive mechanism, short-circuit proof, stabilised |
| Output voltage | Variably jumpered (12 V DC / 24 V DC) |
| Output current | a total of 2 A |
| Primary fuse transformer | T 1.6 A |
Scope of Delivery:
- Power supply unit in housing for surface mounting
- Data sheet with instrallation instruction (English, German, French, Italian or Spanish)
WGDC-2P5 Power Supply Unit
For DC Motors
The Power Supply Unit WGDC-2P5 is suited for motors with a five-pole connection.
Functions and Operation:
- For motors with 5-polie connection (potential-free connections „Up“, „Down“ and „Com“) or drive mechanisms of the Belimo window ventilation system FLS
- Connection clamps are labelled and pluggable
Technical Data:
| Housing | Plastic material |
| Colour | Grey |
| Mounting | On-wall |
| Protection category | IP 54 |
| Dimensions | 60 × 80 × 57 (W × H × D, mm) |
| Weight | pprox. 925 g |

| Operating voltage | 30 V AC, 50 Hz |
| Outputs | 1x 5-pole (up/down/Com) 1 x Belimo FLS (MP/+24 V/GND) short-circuit proof, stabilised, potential-free |
| Output voltage | 4 V DC |
| Output current | 2 A |
| Primary fuse transformer | T 1.6 A |
Scope of Delivery:
- Power supply unit in housing for surface mounting
- Data sheet with instrallation instruction (English, German, French, Italian or Spanish)
