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.
The Korad power supplies are sold with different brand names, but they always feature the same high build quality of Korad.
Models
This device is offered in 2 different setups, which differ in the connections on the front of the device. One model features screw-on connectors, and the other features ‘safety connectors’. Both models are equal regarding their functions and specifications. The screw-on connectors also accept regular wires, but the safety style connectors only accept banana plug connectors.
