Sorensen SG 1000V DC Power Supply Supports High-Voltage Applications
May 8, 2013. AMETEK Programmable Power has extended its Sorensen SG Series high-power DC power-supply line with the introduction of the new SG 1000V, which can supply up to 1,000 VDC.
The Sorensen SG Series is suited for a range of applications, including photovoltaic (PV) inverter and electric vehicle test, semiconductor processing, and electroplating. It can also power CT and MRI scanners that are used as luggage scanners for homeland security.
The new 1000V DC model of SG Series power supplies can provide up to 15 kW in a 3U package. Users also can select from 5 kW and 10 kW models. For users who need more output power, up to five 15-kW units can be connected in parallel to supply up to 75 kW. In addition, the Sorensen SG Series offers fast voltage and current slew rates, low noise, and built-in power factor correction.
All of the models in the SG Series are available with either Sorensen General-purpose Intelligent (SGI) control or Sorensen General-purpose Analog (SGA) control. Units with SGI control combine on-board intelligent controls with the outstanding power electronics common to all SG Series supplies. These controls enable sophisticated sequencing, constant power mode, and save/recall of common setups, making the SGI-capable unit suitable for repetitive testing using complex or compliance waveforms. The unit features a vacuum-fluorescent graphical display in eight languages, context-sensitive soft keys, and a front-panel keyboard. An SG option is a factory-installed dust filter for 3U units.
Units with SGI control come with a standard RS-232C port. GPIB/IEEE 488.2 and LXI Ethernet ports are optional features. Units with SGA control are designed for users who require simple front-panel analog controls or external control. With the same high- performance power electronics as the SGI, the SGA-configured unit provides essential features such as 10-turn potentiometers for setting voltage and current, 3½ digit LED readout plus front panel over-voltage protection (OVP) preview/adjustment and reset. Units with SGA control come standard with remote analog control and can be fitted with an RS-232C port, a GPIB/IEEE 488.2, and an LXI Ethernet port as optional features.
