Where to find the highest power in the smallest package

Series 2268 850W DC Power Supplies provide voltage and current output levels ideal for automated test. They offer maximum voltage outputs of 20V, 40V, 60V, 80V, 100V, and 150V with corresponding maximum current outputs of 42A, 21A, 14A, 10.5A, 8.5A, and 5.6A. They allow outputting any current, including the maximum current, at any voltage. Analog and digital control options and several digital interface options are available. They also have the flexibility to operate in constant voltage (CV), constant current (CC), or constant power mode.

850W in a low profile 1U high, half-rack width enclosure Offers the highest power density in the smallest package to minimize test rack space requirements.
15V and 5V auxiliary outputs Supports driving or signaling external devices, often eliminating the need for additional instrumentation.
Isolated analog inputs Minimizes control line noise, reducing or eliminating the susceptibility to signal degradation.
LAN, USB, GPIB, RS-232, RS-485 interfaces and analog input are all standard Makes it simple to select the optimum interface for any test application.
Operate at temperatures up to 50°C Allows reliable performance even in test racks that have elevated temperatures.
Auto sequence control Supports internal execution of commands to minimize bus communication time.
Foldback mode with programmable delay Shuts down the output on transitions between CV and CC operation to protect voltage- or current-sensitive devices. The programmable delay time eliminates nuisance shutdowns due to transient voltage overshoots.
Two units can be connected in series or up to four units connected in parallel to produce higher outputs Expands voltage or current capacity for higher output requirements.
Numerous built-in safety features: over- and under-voltage protection, overcurrent protection, overtemperature protection, and a hardware interlock Protects the load and the supply.
