With this device from ZKE Tech, you can not only test all kinds of batteries, but also test DC power supplies up to 30 V. You can test the device up to 20 A or up to 200 W, whichever comes first. The four MOSFETs on the heatsink are of type URFP250M. These semiconductors have an RDS(on) of 0.075 Ω and an ID of up to 30 A. The maximum power dissipation is 214 W. Next to the four MOSFETs there is a KSD-01F H090. This is a temperature switch that closes at a temperature of 90 °C. It is used to control the fan. It works at two speeds. When the device is switched on, it works at a low speed. If the heatsink gets warmer than 90 °C, the fan switches to a higher, rather noisy speed. We connected the EBD-A20H to a digitally adjustable power supply and compared its voltage indication with that of our Fluke 8842A reference meter. The results are excellent. We created a series circuit of the power supply, the EBD-A20H and our Voltcraft VC650BT meter and set the current on the EBD-A20H. These results are also excellent.
