High voltage DC power supplies boast fast response with low ripple and noise

Glassman Europe has a new range of programmable, DC regulated power supplies, the GX Series, its most powerful to date. The series is a highly-specified family of 25kW to 200kW fast response, air insulated power supplies, boasting tight regulation combined with low ripple and noise. This comprehensive range has nineteen models in all, from 0 to 1kV through to 0 to 100kV, and individual units can be set up in a master/slave configuration to produce a maximum output capability of 200kW. Input for the rack-mountable series is 480VAC three-phase as standard, with 380VAC and 415VAC input available as an option. The units feature a microcontroller based front panel control and communication interface and there are also integral RS232/USB serial ports as standard, plus an optional Ethernet interface, which enables high-resolution voltage and current programming either on site via the front panel digital encoders or via the analogue remote interface. A time-saving Last Setting Memory feature stores power supply parameters at each AC turn off sequence, saving time. The constant voltage/constant current operation feature utilises automatic crossover between the two to protect against overloads, arcs and short circuits. The series features the company’s proprietary forced air cooling system, with redundant thermal overload protection incorporating temperature sensing and a fan speed monitor. Being air-insulated, rather than encapsulated or oil insulated, the series is lighter in weight and easier to service than competitive power supplies.
