Dual Output, 60V, 20A, 840 Watts - PowerFlex CPX400D & CPX400DP

The CPX400D (RS 7312842) and CPX400DP (RS 7072857) are dual output PSUs using PowerFlex regulation which enables higher currents to be generated at lower voltages within a power envelope. They feature smart analogue controls with settings lock, and isolated voltage tracking for easy series or parallel wiring. The CPX400DP includes a full range of digital remote control interfaces and duplicate output terminals at the rear.

For an optional GPIB module see stock number 144-5481.

Features and Benefits:

Dual isolated outputs, independent or tracking
PowerFlex regulation with 840 watts of total power
Up to 60V and up to 20A within a 420W power envelope on each output
Isolated tracking provides up to 120V in series or up to 40A in parallel
True analogue controls with digital enhancements
S-Lock function locks voltage and current settings at the touch of a button
Range control buttons offers fixed range or PowerFlex operation
Variable over-voltage protection (OVP) and over-current protection (OCP)
Synchronous or independent switching of the outputs
Compact 3U half-rack casing for bench or rack use
Duplicate output and sense terminals at rear (CPX400DP only)
Full range of bus interfaces, RS232, USB, LAN (LXI compliant)

Note

The higher value CPX400DP includes GPIB, RS-232, USB and LAN interfaces with LXI class C compliance
