Korad KA3305P programmable power supply

The Korad KA3305P is a 3-channel programmable power supply with excellent value for money. This device features a very small resolution of 10 mV/1mA, which ensures accurate operation. The output settings of this device can be changed even if the outputs are switched off. This lowers the risk of accidentally breaking a circuit due to overvoltage or overcurrent.

The power supply features 3 channels, of which 2 are programmable between 0V - 30V and 0A - 5A. The third channel is a non-changeable 5V source which can serve as a power source for most regular 5V testcircuits. The 2 programmable channels can be configured to be connected internally in series or in parallel, through the device its settings.

The Korad can be controlled via the supplied software. A connection can be made through either USB or RS232. Next to this, presets can be saved and recovered through the 5 memory buttons on the device.
