Example notebook for AimTTi EL320P

This is the power supply used for the Bluefors 4 K stage warmup heater.

The AimTTi ELP320 a simple linearly-regulated DC power supply supporting constant current or constant voltage operation. The EL320P in particular can source 2 A at 30 V.

from qcodes_contrib_drivers.drivers.AimTTi.EL320P import EL320P

Apply 60 Watts to the 4 K stage during fridge warmup.

heater_addr = 'ASRL3::INSTR'
heater_v = 30 # V
heater_i = 2 # A
warmup_heater = EL320P('warmup_heater', heater_addr)
err = warmup_heater.error()
if err != 'OK':
    print('Heater error: {}. Turning heater off.'.format(err))
    warmup_heater.output('OFF')
else:
    warmup_heater.voltage_set(heater_v)
    warmup_heater.current_set(heater_i)
    warmup_heater.output('ON')
    print('Actual output voltage: {:.2f} V'.format(warmup_heater.voltage_out()))
    print('Actual output current: {:.2f} A'.format(warmup_heater.current_out()))
