POWER SUP PLY CON TROL LERS

Interface between Computer and analog programmable Power Supply.

Features

• IEEE488 or RS232 interfaces designed to be used with analog programmable power supplies

• Voltage and current of the power supply can be programmable and monitored

• Readback of status signals

• Set the power supply in Remote/Local, Remote ShutDown ect.

• Two 14 bit output channels for programming, two 12 - 16 bit input channels for monitoring

• Up to 15 PSC's on one IEEE488 or RS232 BUS to control multiple supplies

• Software calibration, no trimmers

Programming

IEEE488 :

• The PSC 488 programs a power supply through the IEEE488 Bus

• PSC 488 EXT : external module for bench operations or rail mounting

• Note : the PSC 488 models can be also configured for RS232 programming

RS232 :

• The PSC 232 programs a power supply trough the standard serial RS232 port on a computer

• PSC 232 EXT : external module for bench operation or rail mounting

The PSC allows three groups of commands :

• IEEE488.2 Common Commands

• SCPI (standard Commands for programmable Instruments)

• DPC (Delta Programmable Commands) emulation mode of the old PSC44M (for compatibility only)

The PSC can be programmed using languages like Basic, Pascal, C, Visual Basic, Delphi, Hpvee, Testpoint, Labview ect.
Some software examples are available from www.DeltaPowerSupplies.com

Analog outputs Analog inputs

• Two 14 bit analog outputs • Two 12 -16 bit analog input channels

• Software full scale calibration • Software full scale calibration

• Software offset calibration • Software offset calibration

• Linearity error 1 LSB • Linearity error +/- 2 LSB

• TC typical 30 ppm/°C • TC typical 30 ppm/°C

Each analog in- and output can be set or read. Analog voltage are standardized on 0 - 5 V.
Analog in- and outputs have a common zero.

Status monitoring

The PSC privides logic status inputs to monitor the status signals of the power supply as CC mode, current and voltage limit,

DC fail, AC fail, and Over temperature.

Controls

Remote ShutDown : Enables / Disables the output voltage of the power supply.

REMOTE : Switches from manual control to remote control ( not on PSC-488 and the PSC-232 modules)

PSC-488 PSC-232

User Inputs

The PSC-232 module and the PSC-488 module provide two 1000 V opto-isolated logic inputs with common zero for custom use.

The input impedance is 470 Ohm, Logic high = 2.5 ... 8 V, Logic low = 0 V

User outputs

The PSC-232 module and the PSC-488 module provide two 1000 V opto-isolated, logic, open collector outputs with common zero for custom use.
The outputs collector emitter maximum rating is 50 V / 4.5 - 7 mA (total dissipation max mW). See manual for more details.
