A series of linear mode power supplies that combine the low ripple, high precision output of laboratory graded linear regulated power supplies with full remote programming and data logging functionality.
- Choice of DC voltage outputs – 18V, 30V and 60V
- Linear mode for a high precision, low noise output
- Typical applications include research and development, quality control and production - especially where there is a requirement for multiple power supplies with one centralised PC control
- Excellent load and line regulation
- Full remote programming and data logging
- Built-in RS-485/RS232 interface enabling the control and data logging of up to 31 power supplies of different models of this series (requires an RS-232 to RS-485 adaptor available separately, please see below)
- Using supplied software, up to 9 preset voltage and current limits and up to 20 sequential timed steps (100 steps can be stored on computer) may be programmed on the power supply or the PC
- Command set and LabView driver enable users to integrate their own software with the power supply for full remote programming and data logging functions
- Constant current and constant voltage modes with auto-cross over indication on front panel
- 4 digit LED high resolution ammeter and voltmeter with calibration facility
- Tracking over voltage protection with user preset maximum output voltage
- Supplied with user manual, 32-bit Windows control software. LabView driver, command set software, USB 1.0 driver, USB cable, RS-485 connector and 1x 120Ω resistor
