Mastech Power Supply

Newly added: Programmable DC power supply with USB

sean — Sat, 06 Feb 2010 07:56:16 +0000

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

sean — Sat, 06 Feb 2010 07:34:46 +0000

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 gernators.

Mastech Linear Power Supply HY3010D

We have recently added the following Mastech power supplies to our inventory:

Mastech Linear variable DC Power Supply HY3010D

Mastech Linear regulated power supply HY3020D

Mastech Linear regulated power supply HY5005D-2

MASTECH VARIABLE REGULATED DC POWER SUPPLY HY6020E

With these addition, we have not only dramatically increase the choices of linear power supplies, especially the higher current power supplies. HY6020E, with up to 60V in output voltage and 20A in output current, is one of the most powerful power supplies we carry so far.
