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.
