Power Supplies

Hastings power supplies are available in one or four channel versions. They convert 100, 115 or 230VAC
to the ±15 VDC required to operate the instruments and provide a digital indication of the instrument
output. Hastings power supplies are power limited to no more than 150 VA max (fused). Interface
terminals for the analog output signals and a main power on/off switch are located on the rear panel as
well. For safety reasons it is recommended that the power supply (and on/off switch) be kept near the
flow instruments and that the on/off switch not be blocked. Throughout this manual, when reference is
made to a power supply, it is assumed the customer is using a Hastings power supply. Hastings Power
supplies change as new technology becomes available. For knowledge of the most up-to-date Hastings
power supplies, please consult either Hastings sales staff or our website at
WARNING: To prevent the spread of fires in the event of a fault, only use power supplies power
limited to no more than 150 VA. The current available from a power supply used with a 300
Series instrument should be no greater than 1.6 A. Hastings power supplies meet these
requirements.
