MULTIPLE OUTPUT PROGRAMMABLE LINEAR D.C. POWER SUPPLY

The GPD-Series contain the superior technology and high quality which CW lnstek had established through its long history of power supply design and manufacturing. The GPD-Series offers digital panel control, large display, bright LED indicators, high output resolution, 4 sets of setup memory, USB remote control and smart cooling fan control. Additionally, the GPD-Series provide easy operation, a wide selection of panel settings and the most important for a reasonable price. All these features make the GPD-Series the most promising new comer in the power supply market.

High Resolution

With 'lmV/1 mA (for GPD-23035/33035/43035) high resolution and coarse/fine volume control the GPD-Series, guarantees clean and stable output. Using the GPD-Series you can easily simulate the device under test‘s accurate behavior against small changes in voltage or current, which is impossible when using a low resolution power supply.

Tracking Series and Parallel Function

Tracking series and parallel function allows you to use the GPD-Series in wide range of applications. The tracking series mode guarantees higher output voltage, while the tracking parallel mode guarantees higher output current.

Convenience Functions

The knobs are digitally controlled, allowing fine or coarse volume setting. The key lock feature locks panel operations, preventing accidental change of the settings which might lead damaging for the equipment.

4 Sets of Save / Recall

The GPD-Series can save and recall panel settings, these feature which can not offered by general power supplies. You can quickly select a panel setting from four memory sets without manual configuration.

USB Remote Control

The USB device port in the C-PD-Series allows you to remotely control the power supply according to your application needs.

FUNCTION FEATURES

Bright LED display shows settings or actual level of output
The independent CH3 output offers three commonly used voltage settings (C-PD-33035/3303D only)
C.V./C.C. modes are clearly indicated in different colors
Smart cooling fan control offers a well balanced cooling mechanism, ensuring quiet operation
The tracking series and parallel mode can be selected with a single touch
Indicators embedded in the keys provide an instant view of the power supply status; the Key Lock feature prevents improper operation

Exactly What was Needed

5.0

~1 week PS is doing exactly what is needed - 2x adj. and 2.5/3.3/5.0 with overall USB control. Not sure on the knob beefs below; seems that the rate of adjustment of fine knob is a factor (just turn slowly and one gets perpetual 0.1V increments in either direction). One minor comment is that connecting the unit with USB does not seem to elicit the usb - yes/locked display response as indicated in the manual (using USB 1.0 cable, or ID line not being OTG compatible on port or cable?), but *IDN? and all other commands work fine along with the Locked feature - CR/LF on terminal setup ...

Knob adjustment unusable

3.0

Decent power output, relatively quiet. - Unusable knobs. Turn the voltage knob in "Fine" mode 1 click, and get 0.1 V change. Turn the knob a couple of clicks, and change is several volts! A sloppy programming on Instek's part, apparently. They have no intention of fixing it, as problem persisted for at least 4 firmware revisions (1.04 through 1.07). Do not purchase if you rely on knob adjustment. Will do fine if controlled via UART commands only.

Nice power supply

Very nice unit. Good features for the price. It isn't as loud as my other Instek. Hard to beat this unit for the price.

5.0

I just received this item a few days and am really impressed. The USB interface and LabVIEW support are easy to implement. Despite the low cost, it appears to be very solid and have a good build quality (time will tell). So, so far, I can recommend it.

Power poweer everywhere

multiple supplies, dual displays, at that price, what's not to like. We needed to run the supplies in series for a student lab. it worked like a charm.
