- Isolated PC/AT Power Supply Board Programs Under WINDOWS
-
- Delivering a full 22 Watt output, a precision programmable power supply and
- input monitor, configured on an IBM-PC/AT board, has been announced by
- DATEL, Inc. The Mansfield, MA company is offering the multi-channel
- isolated board for programmable linear test applications, custom PC-based
- Automatic Test Equipment (ATE) and software-controlled manufacturing
- usage. The system is excellent for testing power supply variation
- rejection on development circuits.
-
- The new board, model PC-462, includes two unipolar channels of 0 to +20.475
- Volts and 0 to -20.475 Volts at 250 mA maximum, intended for linear test
- circuits. Also included are two 0 to +6.1425 Volt and 0 to -6.1425 Volt
- channels, each delivering 1 Ampere maximum, typically for logic circuits.
-
- All four output channels are isolated from the host PC/AT bus by 250 Volts
- RMS. Each channel is controlled by an independent 12-bit D/A converter
- under software control. Sense feedback offers precise load regulation. The
- output channels are unconditionally stable under all load conditions with
- 0.025% accuracy and linearity on the +/-20 Volt channels. Transient
- response is 200 microseconds.
-
- Both the current and voltage may be monitored on all output channels with
- an on-board, fully isolated 16-channel analog input system. A 12-bit A/D
- converter is used. Four independent external analog inputs and four
- calibration channels may also be measured. Triggering can be either
- internal or external.
-
- Four software programmable isolated digital channels (two inputs, two power
- MOSFET outputs) can control discrete devices. One input may be configured
- as a PC/AT interrupt to flash alarms or do emergency shutdown.
-
- A comprehensive graphic software package, model PC-462SET, written in
- WINDOWS Visual BASIC, offers multi-channel voltmeter display and control,
- engineering unit conversion, digital I/O, calibration, time-stamped file
- save/display mode, automatic overlimit warning and shutdown. Prerecorded
- test sequences from disk may be played back using the system clock for
- automated ramp testing applications. PC-462SET runs under Microsoft
- WINDOWS 3.0.
-
- The PC-462 is configured on a 4.5 inch by 13.31 inch (11,43 x 33,81 cm)
- board filling a long PC/AT slot. PC/AT power is used at +5 Volts 4 Amps
- max and +12 V., 1.5 A max. The PC-462 is $1195 in single quantity with
- generous quantity discounts. A free disk of "C" subroutine library
- software is included. The PC-462SET is $95 and the source code, model
- PC-462SRC, is $395. Delivery is stock to four weeks.
