DCS33-33E M15 - 33V 33A, 1kW programmable power supply (Sorensen) - New / RFE


Sorensen / Elgar 33V 33A Programmable 1kW DC Power Supply, model number DCS33-33EM15. These are new/RFE units that were removed from new custom power assemblies (see picture at bottom). They include an instruction manual but do not include the original box or certificate of conformance. They are in excellent condition and have some very minor marks around the mounting holes because they were previously mounted. These units include the option M15 isolated interface, click here for details (PDF, ~500KB). Each power supply is pre-wired for 240VAC input. By adjusting an internal jumper, the supply can be easily rewired to accept 120VAC input. See product manual for details.
