Save paper, save trees, save earth

Dear User,

We request you to use the Learning material in the CD form

provided with this supply.

Your this act will help to save paper.

Please remember that each paper manual requires 50-100 sheets of paper

on an average.

Your CD learning material has

colourful diagrams,

plenty of theory,

detailed experiments with observation tables,

frequently asked questions, etc.

…….. and more so sometimes videos as well.

RoHS Complian

Scientech Products are RoHS Complied.

RoHS Directive concerns with the restrictive use of Hazardous substances (Pb, Cd, Cr, Hg, Br compounds)

in electric and electronic equipments.

Scientech products are “Lead Free” and “Environment Friendly”.

It is mandatory that service engineers use lead free solder wire and use the soldering irons upto (25 W) that

reach a temperature of 450°C at the tip as the melting temperature of the unleaded solder is higher than the

leaded solder.

Introduction

The Scientech 4077 Multiple Power Supply has been designed as a constant current

(CC) and constant voltage (CV), source for laboratories, industries and field testing

applications, featuring low power loss, compact and lightweight. It provides three

floating independent DC output voltages and is ideally suitable for complex analog

and digital testing.

The DC outputs 0- 30V and 0 ±15V Dual Track, can be continuously adjusted, with

coarse and fine controls. The other DC output 5V also can be adjusted between 4V

and 6V. Current limit is also adjustable for all outputs. Any over loading for adjusted

current limit, is indicated by OR LED. When the maximum setting is crossed or the

overheating has occurred, the OR LED will lit up.

Two displays (one 3-digit display for voltage & other 3-digit for current) are used to

read the instantaneous values. These two displays can be switched simultaneously for

either of the DC outputs. It has low residual ripple and noise, as well as excellent line

and load regulation. The Scientech 4077 Multiple Power Supply is provided with all

protective circuits to ensure trouble free operation
