Since the energy-saving coil is used, it occupies many good features, such as low losses, small volume, high efficiency etc. it is still assembled with input-plug, power-on switch with bulb, fuse etc. hence easy to bring with and safe for use.
This product is one of the new practical and convenient to carry type of the brushcontact, type voltage regulator. The output voltage is indicated by a voltameter thereon for-directly prompting the output voltage correctly. It is suitable for use in any place of unstable power source.
The product can be broadly used in industry, science experiment, home electric apparatus and especially in maintaining work-sites to bring about the voltage-regulating, lightadjusting, temperature-control, power-control etc. It is an ideal a.c. voltage regulating source.
OPERATION AND MAINTENANCE
The source voltage should in accordance with input-voltage value given on nameplate. The case of the product should be earthed effectively.
For operating, set the plug into the source socket first, and then put on the power-switch, then turn the hand-wheel slowly to regulate the output voltage.
Please check the operating condition of the regulation. If the contact brushes wear more bitterly or they are somewhat injured, these brushes should be changed by new sets of the same model, putting a piece of sand-sheet of No. zero under the brushes, turning the brush-frame several times to turn the brushes round. The product should only be used under good contact conditions.
If you bring with the product for use, please take and put down it carefully so as to avoid damage of the meter or the brushes.
