Hi guys I got this power supply that is damaged. No history behind it. Power supply has two separate inputs, V and V, could be that somebody connected it to the wrong input. Also the fuse from the DC line that is coming to this part of power supply.

Version: 2. Make sure of grounding well for the tester before testing in case of damage caused by. Electrostatic induction.

Ther e are good Grounding picture in the right bottom of each. Make sure of grounding well for the relay test set before testing in case of damage. There is the icon to indicating well grounding at. External voltage source or current source is forbidden to be conducted into the output. The voltage circuit can not be short circuit or overload, and the load of the current circuit. When there is overload or short-circui t in the voltage source, the tester will.

When the heavy current output has been c ontinued for a long time and the power. At t hat time, the test will not be continued. If any fault was detected on the tester, pleas e contact the factory or the local agent for. If there is any emergency dur ing the test, please right away exit out the button of amplifier, then shut down t he power supply of the host.

The tester is supposed to bring back to t he package box on condit ion it has not been used. Dear Customers:. Meanwhile, we shall be much. Should any business advice or te chnical support service.

A Excellent linear amplifier for voltage and current with good reliability. Output waveform is of smooth and true; no high order harmonic that be easily generated by electric switch amplifier.

Current source and voltage source have no current booster and no voltage booster, but direct coupling mode is adopted for the sources which enable the output frequency.

And it meet the requirements of transient state test of protection rela ys, consequently to r ealize the purpose of performing simple simulation tests on various protection relays. True and accurate small electricity waveform, no electromagnetic pollution.

Good amplitude frequency characte ristic and transient response. Use the latest DSP and large scale program mable FPGA of American TI Company plus with high precision because of point wave form simulation, enable K10 series with better transient response and frequency-amplitude characteristic. Having applied digital serial port DA, we further improve output precision of K10 series C. Make real sense of simultaneous output in voltage and current of the tester; amplitude value, phase and frequency are individually and continuously adjustable at random.

Older Macintosh Magnetek power supply ressurection. I need some advice repairing it. I slowly got it to work, first I disconnected all the visually blown and shorted components, until all there was left was a standby power supply. There was a major darkening in the standby area, but it was caused by an overheating resistor which still tests good - 68 ohms. This was caused by dried up capacitors, at first I decided not to recap it, but when I tried it first, the power supply drew 20W thorugh the lamp limiter. Recapping made it much happier but still a bit high at 9W. The resistor gets only warm now.
