Product Overview
Teledyne Hastings Model 400 is a bench-top or half-rack panel-mountable power supply and readout unit designed to operate up to four Teledyne Hastings instruments simultaneously. Confirmed by the rear panel label: Model 400, Serial No. 267, manufactured in Hampton, VA. It supplies regulated DC power and supports 4-20 mA analog signal compatibility for mass flow meters, mass flow controllers, vacuum gauges, and pressure transducers. Input accepts 100-125 VAC or 200-250 VAC at 50/60 Hz, making it usable on both North American and international power standards. The internal identifier 247C appears on documentation associated with this unit and may represent a sub-component or configuration code - not confirmed as a standalone model number.

Frequently Asked Questions
Which instruments is this compatible with?
Designed for Teledyne Hastings mass flow meters, mass flow controllers, vacuum gauges, and pressure transducers that use 15-pin D-sub connectors and 4-20 mA analog signals. Verify the connector type and power requirements of your specific Teledyne Hastings instruments before connecting. Compatibility with non-Teledyne instruments is not confirmed.
Was this tested beyond powering on?
Confirmed to power on. The display is active, all knobs and switches are responsive. Full functional testing with connected mass flow controllers or meters was not performed. Verify functional status with your instruments before deploying in a critical process.
What is included with this unit?
The Model 400 unit with desktop stand and attached power cord. No instrument cables, documentation, or accessories are included.
Is RS-232 or RS-485 communication available on this unit?
Not confirmed for this specific Model 400 serial number. Communication interfaces including RS-232 and RS-485 are documented for the later THPS-400 variant. Verify against the rear panel and any available documentation for this exact unit before assuming serial communication is present.
Can cables longer than 25 feet be used with this power supply?
Cable length beyond 25 feet may affect calibration for connected flowmeters and could require recalibration. Verify cable length requirements against your instrument specifications before use.
The rear label says Hampton, VA - Teledyne Hastings has been building flow instrumentation there for decades, and this unit carries that lineage. Four channels, a working display, and a power cord already attached: someone's bench just got a little more capable.
