Hastings’ Power Supplies are designed as combination power supplies and digital readout monitors.
They can simultaneously power a combination of different Hastings Flow Instruments. The front panel
(9.47"H X 3.47"W) allows mounting of two units in a standard 19" rack. A terminal strip on the rear
panel provides the user with continuous analog outputs from all channels. All power supplies have a 3-1/
2 LCD display.
Models 200 and 400 Power Supplies can accommodate up to two or four Hastings Flow Instruments,
respectively, and the Model 40 is for use with flowmeters only, powering up to 4 simultaneously. The
Model 40 also features user-adjustable gas conversion factors for direct reading when changing
gases. For more information, request Product Bulletin No. 544.

The Model AL-1 Flow Alarm is available as an attachment suitable for use with any 0-5.00 VDC input
signal. Calibrated digital dial precision pots determine the low and high set points as a percent of full
scale. This permits use with any range flowmeter or other instrument having a 0-5.00 VDC linear
output signal. Control action is within 0.2% of scale. The AL-1 is available in the panel mount J
package.
