Benchtop power supply

The ES150 series has excellent lifetime and stability. Multiple power supplies can be connected in series, parallel or both in series and parallel to create numerous output configurations. Due to its small size, the unit is extremely suitable as a bench top power supply.

Standard, the ES150 can be controlled either via the front or an analog input at the rear of the power supply. Optionally, Ethernet and RS232 remote programming features can be factory installed. Furthermore, external interface modules are available to add this functionality to existing units.


High isolation voltage

The output terminals are floating and isolated up to 600 V DC. Combined with the optional 19" mounting, the power supply can be integrated into larger systems easily to power main or auxiliary devices.

Optional factory installed features

Rear Power Output and Remote Sensing
Rear Power Output and Remote Sensing

Output terminals at the rear panel instead of binding posts at the front panel, includes remote sensing. For more information, download the data sheet ES150 series (see pages 1-5 & 1-6).

Increased Output Power
Increased Output Power

For conservatively rated units, extra output power (with the same reliability) is allowed. At some derating, either the maximum output voltage or current of these units can be increased by about 10%. Contact us or our local distributor for information which units extra output power is allowed.

Secured Voltage and Current Setting
Secured Voltage and Current Setting

For maximum security the settings for CV and CC can be adjusted with a screwdriver only and are protected with a plastic cap from accidental adjusting.
