Saelig offers PSU-series power supplies
November 30, 2016 | By Manufacturing AUTOMATION
Nov. 30, 2016 – Saelig has introduced the PSU-series of single output programmable switching DC power supplies that can provide up to 200A current and cover a power range up to 1520W.
Described as “high efficiency, high power density,” the series includes five models from 6V to 60V rated voltages. The models can be connected in a series for increased power capacity: up to two units in series or up to four in parallel to cover a broad range of applications. The PSU-Series of 19 in. rackmount (1U) single channel power supplies from GWInstek provide constant voltage/constant current selection, a useful safety feature for protecting a Device Under Test (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, says Saelig, adding that running in constant current mode limits current spikes, protecting the DUT from inrush current damage. The Over-voltage (OVP) and Over-current (OCP) protection levels can be selected from 10 per cent to 110 per cent, with the default level set at 110 per cent of the power supply’s rated voltage/current. The series provides USB Host, USB Device, LAN, RS-232 with RS-485, and isolated analogue control interfaces 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.
