The Elgar DCS Family comprises 1 kW, 1.2 kW, and 3 kW DC programmable switching power supplies that use switch-mode technology to achieve high power density in a low-profile chassis. Through its packaging approach, the series delivers continuous full output power—1 kW, 1.2 kW, or 3 kW—in any voltage and current combination within each model's rated output limits. Voltage and current settings are adjusted with 10-turn potentiometers and displayed simultaneously, while front-panel LEDs indicate overtemperature, remote programming, shutdown, overvoltage protection, status, and constant-voltage/constant-current mode operation.
A programmable DC power supply provides regulated, adjustable direct-current voltage and current for powering and testing electronic devices and subsystems on the bench or within automated systems. The DCS series supports selectable remote programming of voltage, current, and overvoltage protection, and offers a remote start/stop and interlock input that is TTL compatible or driven by an AC voltage signal or a contact closure, allowing the supply to be integrated into a larger controlled test setup.
ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit we sell is inspected and functionally verified in-house before it ships, while new units leave the building factory-sealed exactly as received, so buyers receive equipment handled to a consistent standard whichever condition they choose.
Elgar Electronics Corporation was a San Diego-based manufacturer of programmable power sources that became part of AMETEK Programmable Power following AMETEK's acquisition of the business.
The DCS Family is organized into three power tiers—1 kW, 1.2 kW, and 3 kW—each offered in a range of fixed voltage/current models identified by an output suffix, from the 0-8 VDC models through the 0-600 VDC models. Every model delivers its full rated power continuously in any volt/amp combination within its rated voltage and current limits.
All three tiers share the same core architecture: switch-mode conversion, 10-turn voltage and current potentiometers with simultaneous display, 0.1% line and load regulation, crowbar overvoltage protection, and the same internal-interface option set. The tiers differ primarily in total output power, chassis size, and input-power configuration.
Each model in the family below is its own dedicated product page with condition-matched pricing for pre-owned units. Compare the voltage and current ratings across the models to match the supply to your output requirement, then select the listing for the specific model and condition you need.
The clearest difference between the tiers is output power and packaging. The 1 kW and 1.2 kW models share a 1U, 1.75-inch-high, 19-pound chassis and run from single-phase AC (100-132 VAC or 200-250 VAC), whereas the 3 kW model uses a 2U, 3.5-inch-high, 33-pound chassis and accepts three-phase 190-250 VAC or single-phase 200-250 VAC, limited to 2.5 kW on single phase.
Within each tier, the individual models set the voltage and current envelope, spanning 0-8 VDC to 0-600 VDC and 1.7 A to 350 A across the family; consult the comparison table for each model's exact ratings, ripple, and efficiency. The 3 kW models also add push-button control of standby, OVP reset, and remote/local selection, and regulatory coverage differs in that UL1012 and CSA 22.2 #220 apply to the 1 kW and 1.2 kW models. Match every capability to the specific model's row in the table before ordering.
