Programmable power supplies

Within the programmable power supplies portfolio are DC, AC and linear designs for applications up to 5kW. All models are cost-effective, says Aspen, and are characterised by APM Technologies’ excellent design and build quality.

The rack-mounted SP series DC power supplies exhibit voltage and current measurement capability. It has a standard 19inch rack mount configuration. APM offers 23 models with power ratings up to 1.6kw in a 1U design and 23 models with a power rating of 4kw in a 2U design. Output voltages range from 20 to 200V DC. The SP series design offers up to 92 per cent efficiency. In addition, the SP series provides high precision with up to 0.05 per cent voltage accuracy and 0.1 per cent current accuracy with up to 80m/s no load voltage drop time and 10m/s full load voltage drop time.

The APM SP series can be operated in a master-slave configuration with one master and up to nine slaves. They also feature RS232, RS485, local area network (LAN), universal serial bus (USB) interfaces supplied as standard. A general purpose interface bus (GPIB) is also available as an option.  All 2U configuration supplies also offer standard automobile electrical test curves.

Over the temperature range 0 to +40 degree C the SP range can be relied upon for high stability with continuous and stable working in full load voltage for prolonged periods.

All APM power supply products are accredited to CSA, UL, CE and FCC standards.
