TTi CPX400S 高直流电源,CPX400S数字稳压电源
CPX400S, SA & SP, Single Output 60V, 20A, 420 Watts PowerFlex
The CPX400S is a single output version of the best-selling CPX400 series of dual ouput PowerFlex PSUs. It is available in three versions, manual control only (CPX400S), with isolated analogue remote control (CPX400SA) or with a full range of digital bus interfaces (CPX400SP). The ultra compact design uses minimum space for bench or rack, and remote control versions include rear terminals.
PowerFlex regulation with 420 watts of total power
Up to 60V and up to 20A within a 420W power envelope
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)
Ultra-compact 3U quarter-rack casing
Rear terminals in addition to front terminals (CPX400SA & CPX400SP)
Galvanically isolated true analogue remote control (CPX400SA)
Full range of bus interfaces, RS232, USB, LXI compliant LAN and GPIB (CPX400SP)
