Short Description

Romtek makes available a wide range of fully solid-state Regulated D.C. Power Supplies with most sophisticated features. These features are outlined here and are indicated in the specifications tables. Being fully solid state, the supplies are incomparable where reliability and good performance are important.

Romtek Model: 3160R Multioutput Power Supply has been designed to reduce clutter on the laboratory table. It has not only got all the voltage outputs which are possibly required in the laboratory, but it has got one digital Voltmeter and 1 Digital Ammeter also. It has got an output of 0 to 30V, 2A to take care of transistorized circuits and 2 Outputs of ±3 to ±15V to take care of operational Amplifiers etc and an output of 5 ± 5V, 5A to take care of digital integrated circuits. Digital Voltmeter Provided has 31/2 Digit seven segments LED display and has an accuracy of 0.1%. It enables correct setting of output voltage. The Digital Voltmeter Provided has got 31/2 Digit seven segments LED display and has an accuracy of 0.5% permitting correct setting and reading of current limit and current consumed. Meter selector permits selection of the digital meters so that they can read any of the four outputs. All these facilities are available in a compact size measuring approx. 425mm (w) ´ 150mm (h) ´ 375mm (d). Purchase of a single model 3160R will save you the trouble of purchasing four power supplies, one digital Voltmeter, one digital Ammeter and also save you a lot of interconnecting wires when a practical is set up. Apart from utility as discussed above, all the power supplies in the model 3160R feature excellent ripple characteristics and exhaustive protection circuitry.
