NAME

Electronics::PSU::DPSxxxx - control a DPS power supply

SYNOPSIS

use Future::AsyncAwait;

use Electronics::PSU::DPSxxxx;

my $psu = Electronics::PSU::DPSxxxx->new( dev => "/dev/ttyUSB0" );

await $psu->set_voltage( 1.23  ); # volts
await $psu->set_current( 0.200 ); # amps

await $psu->set_output_state( 1 ); # turn it on!

DESCRIPTION

This module allows control of a RDTech DPS-series power supply, such as the DPS3005, when connected over a serial port.

Interface Design

The interface is currently an ad-hoc collection of whatever seems to work here, but my hope is to find a more generic shareable interface that multiple differenet modules can use, to provide interfaces to various kinds of electronics test equipment.

The intention is that it should eventually be possible to write a script for performing automated electronics testing or experimentation, and easily swap out modules to suit the equipment available. Similar concepts apply in fields like DBI, or Device::Chip, so there should be plenty of ideas to borrow.

METHODS

set_voltage

await $psu->set_voltage( $volts );

Sets the output voltage, in volts.

set_current

await $psu->set_current( $amps );

Sets the output current, in amps.

measure_output_voltage

$volts = await $psu->measure_output_voltage;

Returns the measured voltage at the output terminals, in volts.

measure_output_current

$amps = await $psu->measure_output_current;

Returns the measured current at the output terminals, in amps.

measure_input_voltage

$volts = await $psu->measure_input_voltage;

Returns the input voltage to the PSU module, in volts.

set_output_state

await $psu->set_output_state( $on );

Switches output on / off.

read_model

$model = await $psu->read_model;

Returns the model number (e.g. 3005 for DPS3005).

read_version

$version = await $psu->read_version;

Returns firmware version as an integer.
