TDK/Lambda ESS300-33 Programmable DC Power Supply 300V 33A 10kW
Description
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. The 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.
Features
- Front Panel Adjustable OVP protects load
- Thermal Protection includes LED indicators
- Pulse-by-Pulse Current Limit for fast recovery
- Parallel or Series Operation
- Transient Protection
- Phase Loss Detection (neutral loss detection included above 208 VAC inputs)
- Failsafe Soft Start
- Power Factor 0.9, Efficiency 85% lowers operating costs and heat generation
- Optional internal RS232/IEEE 488 interface
- Ten Turn V/I Potentiometers standard
- Voltage and Current, Program and Monitor are 0-5 V standard (0-10 V optional)
- Output Switching Frequency 240-260 kHz
- UL/CE on selected models.
- CV/CC with automatic crossover and mode indicator
- “Super Sense” provides both voltage and current monitor at the load. This also allows meters to read at the load. (OVP stays local to protect the load and power supply)
