PG501

The WIENER PG501 is a 1.8 kW / 20A class programmable bipolar current source for magnets. The power supply is based on the 3U high 19" PL506/512 chassis design with power bin and a plug-in power supply box which allows replacement of power supplies in shortest time without use of any tools.

The primary DC power supply is using high efficiency WIENER power modules in low-noise switching technology. The bipolar current outputs are generated from a true Four-Quadrant converter and are capable of both sourcing and sinking power. This design also guarantees smooth and continuous transition through zero current.

Using a high precision / high stability current shunt measurement circuit and control loop an excellent accuracy in current setting, reproducibility as well as stability is given.

The PG501 bipolar current source features local and remote monitoring and control including current set points, ramp rates and limits. For remote monitoring and control the power supply provides USB and Ethernet ports and compatibility to the standard WIENER protocols (SNMP, web-ready).
