Benchtop power supply

The ES150 power supply is a robust small power supply, making it a versatile solution for many applications. It boasts excellent dynamic response to load changes, low ripple, great EMC performance, and protection from all overload and short-circuit conditions. The output terminals are floating and isolated up to 600 V DC. The unit is convection-cooled, meaning it does not have a fan, resulting in silent, reliable, and high-performing operation. Consult the data sheet for more information.


The power supply can be programmed either through the front panel or via the analog interface on the rear. Optionally, Ethernet and RS232 remote programming features can be factory-installed; refer to the options or data sheet for more information. Additionally, external interface modules are available to add this functionality to existing units by selecting one of the available external interfaces. Multiple power supplies can be connected in parallel or series using a parallel or series adapter.


The power supply comes standard with foldable feet, making it ideal for bench top use. Alternatively, a variety of 19” rack adapters can be ordered to mount the units individually or in combination in a rack.

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.
