Benchtop power supply
The ES300 power supply 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 benchtop power supply.
Standard, the ES300 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 600V DC. Combined with the optional 19" mounting, the power supply can be integrated into larger systems easily to power main or auxiliary devices.

Options
Optional factory-installed features
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 ES300 (see pages 1-3 & 1-4).
Increased Output Power
Select models support ~10% extra output power (with derating), while maintaining reliability. Either voltage or current range can be increased. Contact us to check availability per model.
Additional programming interfaces
An extra interface can be factory-installed alongside the standard analog:
- ETH2 Ethernet card incl. sequencer and web interface
- RS232 card for serial programming
