Setting current limit is easy on our new DC power supplies

 

We have added some new models of DC power supplies, which have disabled the short circuit protection mode. these power supplies include the HY1503D, GPS-3030D, GPS-1850D, GPS-3050D, HY3003DX, HY3005DX, GPR-1810HD, GPR-6030D, GPC-3030D, HY3005D-3 New Model, HY3006D New Model, HY3010D New Model, HY3010D-3.

With these new models, it's easy to set the current limit. You simply short the output terminals (between + and - terminals), and adjust the current to the level you want. Then disconnect the short and connect the load of your choice.

New arrivals: function generators ranging from 2MHz to 25 MHz

 

We are pleased to annouce the arrival of three new function generators:

  • 2 MHz function generator with built-in frequency counter SFG-1002
  • 3 MHz DDS function generator SFG-2003
  • 25 MHz DDS function generator w/frequency counter, sweep, AM & FM SFG-2120

 Together with our existing 5MHz model (Quakko 5000), we now carries a complete lineup of function generators from entry level to high end models.

Newly added: Programmable DC power supply with USB

 

We have added a new model of programmable DC power supply, model HY3005DP.

The output of this highly stable, high quality DC power supply is continuously adjustable at 0-32V DC and 0-5A.

With its full digital control and 5 memory settings, it's extremely easy set up the output you want and repeat the settings you use regularly.

What's more, you can use the USB interface and software that comes with the unit to program a waveform, essentially use this power supply as a simple arbitrary waveform generator.

The unit comes with very bright LED displays, providing accurate readout for the voltage and current values. This unit has toggle switch at the back that allows you to operate it in 110V AC or 220V AC.

New Switching Power Supplies with over-voltage protection

We are pleased to announce the arrival of EX models, a new line of switching power supplies that have built-in over-voltage protection, over-current protection, and over-temperature protection. The EX models are best suited for the following applications:

 

  • battery charging for Lithium Polymer (LiPo), Lithium Ion, Lithium Manganese, A123 (LiFePO4), NiCd, NiMH, Lead Acid batteries (Flooded, Gel, AGM, SLA), etc.

  • as electroplating and anodizing rectifiers

  • electrolysis, hydrogen generator, fuel cell applications, etc.

  • DC motors, slot cars, aviation applications, etc.

with the over-voltage protection, you no longer need to worry about reverse EMF feeding back into the Mastech power supplies and damaging the power supplies. You can even accidentally hook up the battery with the wrong polarity, and the power supplies will be fine. If you turn off the power supply while the DC motoring is running, that's fine too. In a nutshell, much more robust and much more versatile.

 We also added HY3080EX, and HY30100EX, capable of outputting up to 80A and 100A respectively, excellent for applications that require large current like anodizing, electro-plating, and hydrogen generators.
