Precision DC voltage supplies suit a variety of test and operational applications

Saelig Company has introduced the PSU-HV Series of single output programmable switching DC power supplies that can provide up to 15A current and cover a power range up to 1560W. These high efficiency, high power density 1U-height supplies include five models from 100V to 600V output. More than one unit can be combined for increased power capacity. Made by GW Instek, the PSU-HV series has five models (100V/15A, 150V/10A, 300V/5A, 400V/3.8A, and 600V/2.6A) to satisfy many high voltage application demands. The PSU-HV Series of 19" rackmount (1U) single channel power supplies provide Constant Voltage / Constant Current selection - a very useful safety feature for protecting a DUT. The power supplies normally operate in constant voltage (CV) mode when turned on, but, if connected to a capacitive load, this could cause a high inrush current or current-intensive load at the power output stage. Running in constant current mode limits current spikes, protecting the DUT from inrush current damage. The OVP and OCP levels can be selected from 10% to 110%, with the default level set at 110% of the power supply's rated voltage/current. The series comes with USB Host, USB Device, LAN, RS-232 with RS485, and isolated analog control interface as standard. A LabView driver is also available for rear-panel external control of Power On/Off and external monitoring of the power output voltage and current.
