KNX PowerSupply PSU640

Order no. 31320-20-03
Dimensions (L x W x H) 92 / 50 / 58 mm

With only three division units (54 mm) IPAS offers one of the smallest KNX power supplies with integrated choke. It is designed for 640 mA in a DIN rail housing and can be operated with operating voltages from 180 to 264V AC. The unchoked voltage of 28V DC is also available for the connection of KNX devices that require a separate supply voltage.

Type: Visualization/Automation functions

Application
The KNX power supply unit provides the KNX bus voltage up to a load of 640 mA. An AC voltage of between 180 and 264 V can be selected as the input voltage. A second output provides the unchoked 28V DC voltage which can be used for KNX devices that require an additional supply voltage. Screw terminals (180 to 264V AC and 28V DC) and a standard bus terminal are used for the connection.

Installation
Screw terminals (180 to 264V AC and 28V DC) and a standard bus terminal are used for the connection. The power supply unit can be mounted on a 35 mm DIN rail. The short-circuit proof KNX power supply is protected against overload and overvoltage and has a reset button.
 
Status indicators
3 colour LEDs signal the operating states: normal mode, overload and reset. The KNX power supply is cooled passively.
