MASTECH DC LINEAR POWER SUPPLY VARIABLE 0-30V 0-5A

May 2, 2012 by

This is brand new professional DC regulated power supply from Mastech, Model number HY3005D-3. This high quality power supply has three outputs: two outputs are continously adjustable at 0-30V DC and 0-5A, and the third output is fixed at 5V DC and 3A. What’s more, the two outputs can be used either in independent, series or parallel mode, providing either two independent outputs, or one output with twice the voltage or twice the current output, up to 60V or 10A. The unit comes with 4 backlit LCD displays, providing accurate readout for the voltage and current value for both outputs.

Mastech Dual DC Linear Power Supply 0-50 V 0-5a

May 2, 2012 by

For sale is a brand new lab grade DC regulated power supply from Mastech, Model number HY5005-2. This high quality power supply has two outputs that are continously adjustable at 0-50V DC and 0-5A. What’s more, the two outputs can be used either in independent, series or parallel mode, providing either two independent outputs, or one output with twice the voltage or twice the current output, up to 100V or 10A. The unit comes with 4 bright LED displays, providing accurate and clearly visible readout for the voltage and current value, both in well-lit and dark environment. LED displays are much brighter nowadays, more durable than LCD displays; for this reason they are the new trend in the instrument panels. This unit has toggle switch at the back that allows you to operate it in 110V AC or 220V AC.

  • Smoke detector circuit May 22, 2013
    A smoke detector is part of a sophisticated alarm system. Which within the system is a professional, most will include Section detector gas, room filling ions. Or sensitive to radio signals. However, this circuit does not have to be so complicated. Just another 2 LDRs and LED detection. Only the number of IC LM1801, the circuit helps the device is much less. […]

  • Fuse status indicators for 12 volts power supply May 21, 2013
    This circuit is a Fuse status indicators for power supply 12V. If a fuse is normally, the LED is going to lights all the time. But when it lacks, the LED will be blinking. The value of this equipment in the circuit is suitable for a 12 volt power supply. However able to change the power supply 6 volt or 24 volt, By reducing the value of the resistor to half […]

  • Logic probe tester circuit May 17, 2013
    They are digital logic probe circuits that you make easliy. Most digital circuits that used CMOS ICs. because I like using CMOS ICs. Because it needs a voltage of approximately 3V to 12V and the power consumption is low. If we use the battery power for longer than IC-TTL. But when problems need to Logic. We use a CMOS IC is suitable or more efficient. And in […]
