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.

output signal. Control action is within 0.2% of scale. The AL-1 is available in the panel mount J
package.
