Low-cost power supply has sequencing software

Supplied complete with Windows-based software which allows the user to build timed or triggered sequences of voltage and current settings and simultaneously view the status on a PC

The EL302P from TTi (Thurlby Thandar Instruments) is a digitally controlled version of the popular EL302 30 V/2 A laboratory bench power supply that can be remotely operated using a personal computer.

A simple Visual Basic applet is also included for users wishing to write their own application or to incorporate this power supply into an existing test program.

The EL302P incorporates an opto-isolated RS-232 interface and offers a low-cost solution for a basic programmable PSU that is sufficient for many applications where the sophistication and complexity of GPIB are not needed.

Voltage and current levels are set digitally using either the RS232 bus interface or the local controls.

Setting resolution is 10mV and 10mA.

The all-linear regulator design provide very low output noise (less than 1mV) and fast recovery from transients.

A simple command set allows remote control of voltage, current and output enable along with readback of metering values and operational status.

Local control is via three rotary encoders providing rapid and accurate setting of voltage and current during bench use.

The front panel controls can be locked out when required, making the unit particularly useful in production and test environments where settings must remain fixed.

The EL302P retains the same compact size as other EL Series single-output power supplies, measuring 260x160x295mm, and operates without any cooling fan.

The EL302P costs £229 (plus VAT) in the UK.
