Instruction Manual

1. INTRODUCTION

The BK Precision Analog and Digital series are high quality

serial control type DC Regulated Power Supplies. These models

can be operated at constant voltage or constant current mode

whose output can be varied from 0 up to the rated values for

respective model.

It is a compact unit provided with separate voltage and

current meters (Analog for 1620A, 1622A, 1626A and 3-digit

LEDS for 1621A, 1623A, and 1627A series) for monitoring the

output voltage and current simultaneously. In terms of

operability, these units enable high precision, continuous

variability via coarse and fine adjust knobs. The BK Precision

Analog and Digital series can be connected in parallel with

multiple units of the same model set up a “master/slave”

configuration to increase the output current capability. Serial

connection of multiple units can be used to increase the output

voltage level.

This family of power supplies provides clean and stable DC

output which is most suitable for many areas including

laboratory, industrial, field service, hobby, and telecommucation

applications.

2. FEATURES

• The BK Precision Analog and Digital series are constant

voltage / constant current power supplies which feature

excellent line and load regulations, low ripple and noise

characteristics.

• The units feature separate voltage and current meters so

that output voltage and current can be monitored

simultaneously.

• Output voltage and current can be adjusted continuously

in full range to any desired values. Adjustment can be

done easily and precisely by using separate coarse and

fine adjust knobs.

• The constant current circuit operates to protect against

overload and output short circuit. The limiting current

values can be preset in the full range of the rated values

for respective model.

• Multiple units of power supplies of same family can be

connected in series to provide higher output voltage.

• Multiple units of power supplies of SAME model can be

connected in parallel (master / slave configuration) to

achieve higher output current.
