Single-Unit 0 - 30V / 0 - 2A Regulated Power Supply with Digital Voltmeter
/ Ammeter
| A stand-alone
high quality laboratory power supply that comes equipped with an
easy-to-read digital display for both voltage and current. Its unique
feature is that the heatsink, potentiometers, and output terminals
are all mounted on the PC Board so only the transformer secondary
wires require external connection. The circuit incorporates a current
limiter, which provides overload protection. This allows for continuous
maximum current adjustment from approximately 0 to 2A. An overload
indicator LED is also incorporated as well as coarse and fine voltage
adjustments. Supply voltage: 24 to 26V AC @ 2A and 18V AC C.T. @
300mA. |
