Request a quoteProduct overview
Ceyear 1769 high-power programmable DC supplies offer 5/10/15 kW models, up to 500 V, and model-dependent maximum currents of 30/60/90 A. A 3U chassis provides autoranging CV/CC/CP operation, remote sensing and parallel-system support for development, production and high-power supply testing.
Key functions
- Autoranging output supports constant-voltage, constant-current and constant-power modes.
- Supports voltage, current and power measurements plus remote voltage sensing.
- Overvoltage, overcurrent and overtemperature protection.
- LAN, USB and GPIB remote control plus analog programming.
- Up to seven power supplies of the same model can operate in parallel; a combination of 15 kW models can form an output system exceeding 100 kW.

Application and selection notes
Maximum power, voltage and current are individual limits, not simultaneous operating points. Autoranging output is limited by the rated power of the selected model.
Ripple RMS and peak-to-peak values use different measurement bandwidths: 20 Hz–300 kHz and 20 Hz–20 MHz. Rise/fall times refer to 10%→90% / 90%→10% of rated voltage; distinguish loaded and unloaded conditions.
Use same-model supplies for parallel systems according to the manufacturer configuration, including current sharing, wiring and protection. Actual combined power and input requirements are defined by the system configuration.

Ordering and delivery
Typical MOQ is 1 unit; configuration and delivery are subject to the formal quotation.
