2. FEATURES 1. INTRODUCTION • 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 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.

4. PRECAUTIONS FOR USE 4.3. OPERATING ENVIROMENT 4.1 . CONFIRMING THE SUPPLY RANGE The unit must be used within its specified range. The rated input voltage can be found on the rating table under the unit. Before plugging into the AC supply outlet, check if the input rating conforms to your local supply. For certain models, a voltage selector is available, switch the voltage selector to the correct position before use.

5.2 REAR 13. Master / Slave switch Used during “master / slave control” parallel operation in MASTER / SLAVE configuration. For normal operation, switch should be set to MASTER. 14. In / out terminals for Master / Slave operation Control terminals for use in the “MASTER / SLAVE control” parallel operation mode. 15. Heat sink Heat sink for the power supply. Be careful as this area can become quite hot during operation. 16. Main Fuse 17.

6. OPERATION PROCEDURES 6.1 . STAND-ALONE OPERATION • When using the power supply in stand-alone mode, simply operate by manipulation of the panel switches and adjustment knobs as needed. However, be sure that MASTER / SLAVE switch is set to MASTER position. 6.2. SERIAL CONNECTION Two or more units of the power supply can be hooked up in series to achieve higher output voltage. The resulted output will be sum of the outputs of the individual units.
PAGE 11
6.3. PARALLEL OPERATION (MASTER / SLAVE CONTROL) Two or more units of the same model can be hooked up in parallel to give an increase in output current capacity. The total output current capacity will be the sum of the output currents of the individual units. In this mode of operation, one supply will act as the master and all settings are from the master unit • Note: When connecting the supplies in parallel, be sure that all the power supplies are turned OFF. • HOOK-UP PROCEDURES 6.

7. MAINTENANCE WARNING: The following instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing other than those contained in the operating instructions unless you are qualified to do so. 7.1 MAIN FUSE REPLACEMENT However, calibrations should be attempted only if a 3½ digit multimeter with an accuracy of +0.5% DCV or better and a 0 to 50ohm, 250 Watt adjustable resistive load is available. If re-calibration is required, use the following procedures.

7.3. VOLTAGE CALIBRATION 2. Adjust trimmer VR-5 fully anti-clockwise (referring to the component side). 1. Connect the multimeter to measure the DC voltage across the power supply (+) and (–) output terminals. 3. Adjust the output voltage to the maximum allowable output for respective model. 2. Turn on the power supply, and turn the panel VOLTAGE adjustment knob fully clockwise (maximum output). 4. Adjust the variable resistive load to obtain (Imax +0.1) ±0.02 Ampere on the multimeter.
