The
ESS is a high power Constant Voltage, Constant Current Programmable
DC power supply. Since its introduction in 1995, the ESS has evolved
into one of the most reliable, compact, high performance power
supplies available. It features a pulse-by-pulse current limit which
provides excellent performance in demanding high current
applications such as RF Amplifiers, DC Motors and Magnetic Coils.
The many standard features make it an excellent choice for both OEM
and laboratory applications.
This very high density supply provides 10 kW
or 15 kW in a 5U (8.75") high rack-mount package. Outputs are
available to 600 V (500 V, 15 kW) and 1400 amps.
Front panel includes potentiometers for voltage and current control
along with meters for both. LED indicators clearly show Overvoltage
Condition, Inverter Failure, Phase Loss, and Control Failure.
In addition to Front Panel Controls, the Rear Panel offers analog
programming and monitoring of voltage and current as well as an
optional RS232/IEEE 488 interface. For
higher power systems, ESS power supplies may be connected in series
or parallel. Contact factory for details
Lambda Americas can provide a wide range of custom features in the ESS
package. Some of them include: special front panel color, safety and
control interlocks, custom voltage and/or current outputs, and
precision current monitor.
