The devices in the PGU-MOD series are designed for pure computer operation. The design is significantly smaller than that of standard PGU devices. PGU-MOD can have 1 to 4 channels. With a current range of 200mA to 100nA or 100mA to 10nA, most applications can be handled. The interface and our EcmWin software are included in the scope of delivery. When connecting multi-channel devices to a computer, EcmWin is started several times so that each module can be operated separately, thus making the full range of functions available for all devices.
