High-Precision Current and Voltage control for the most demanding applications at higher power - ALL IN ONE!

The FAST-PS-1K5 series is the new generation of bipolar power supplies by CAEN ELS and it is designed in order to have state-of-the-art performances both in current- and voltage-control modes. Models up to 100 A and up to 95 V are available in order to satisfy any need.

The use of a 0-FLUCS DCCT as the sensing element, combined with thermal stabilized electronic sections, make this power supply have the lowest temperature dependence on the market at less than 1 ppm/K.

Battery Testing and Superconducting Magnets with Source/Sink Capabilities

A NEW optional 19"-1U crate was designed to enable the 4-Quadrant operation at the 1.5-kW full-power. This unit is available for the 100 A - 15 V model and the 50 A - 30 V power supplies. This unit is connected to the power supply by a dedicated power cable that allows the system to operate both as power source and power sink. The specifications, in terms of stability, noise, temperature coefficient, etc. are maintained respect to the stand-alone FAST-PS-1K5 unit. Battery testing - e.g. charge/discharge - as well as superconducting magnet ramp-down procedures have never been easier!

Low-noise and the lowest temperature dependence on the market at 1 ppm/K

The 10/100/1000 Ethernet connection and the two SFP slots allow controlling the power converter in different modes.

The control loop, as for most of CAEN ELS power supplies, is digital in order to obtain the maximum flexibility and easiness of configuration to any connected load – e.g. resistive, capacitive or inductive.

Quench protection for SuperConducting (SC) magnet applications

The FAST-PS-1K5 can be controlled either in current- or voltage-control modes and both control loops can be remotely configured.

Internal protections – e.g. over-voltage, over-current - are implemented as well as external interlocks are present. A quench protection feature is embedded in order to use these power units with superconducting magnets.

Features like waveforms, triggers, etc. are also present in these state-of-the-art units that also embed a Linux OS to give the maximum flexibility.

An embedded Web-Server also includes an oscilloscope feature with the possibility to monitor 4 channels - e.g. output current and voltage - at 100 ksps.

The units can be also locally controlled via a display and a local interface in order to set or monitor the main parameters and status of the power supply.
