Glassman announces the GX series, its highest power DC supply to date

The GX series of programmable, DC regulated power supplies have been introduced by Glassman Europe. There are 19 models in the series of 25 to 200kW regulated high voltage DC power supplies, which have fast response with low ripple and noise, says Glassman.

The GX series of air insulated power supplies have tight regulation combined with low ripple and noise and ranges from 0 to 1kV through to 0 to 100kV. Individual units can be set up in a master/slave configuration to produce a maximum output capability of 200kW.    

Input for the rack-mountable GX Series is 480V AC three-phase as standard, with 380 and 415V AC 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, and 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. The constant voltage/constant current operation feature uses automatic crossover between the two to protect against overloads, arcs and short circuits. Adjustment between constant current and current trip is easily selected via a rear panel switch. Output features continuous, stable adjustment from zero to rated voltage or current by panel mounted optical rotary encode or by external 0 to +10V signals. 

Efficiency is typically greater than 80 per cent at full load and ripple typically less than 0.1 per cent RMS of rated voltage at full load. To prevent arcing, the GX Series power supplies feature both arc quenching and an automatic arc count. The HV output is inhibited after each load arc and internal circuitry continually senses and integrates arcs which occur over a given time period, so that should system or load arcing exceed factory-set parameters, the unit automatically cycles off, clears the fault and re-starts after a set time period.

The GX series features Glassman’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 GX series power supplies are lighter in weight and easier to service than competitive power supplies, says Glassman.

The GX series models are available now, supplied with a three-year warranty for standard versions. Original equipment manufacturer (OEM) and modified models are warranted for one year.
