Arrived in less than a week from CZ, in good condition. Works as advertised, it's a very decent DC load for the price. Supports MODBUS-RTU protocol over RS485 or RS 232, up to 115000 bps (defaults to 9600) , which is the main motivation for my purchase. Modbus registers are documented in the accompanying manual. The banana sockets are a bit too wide for a good contact with regular banana plugs, one should use spade or ring terminals on a connecting wire. The four screws on the back are electrically connected with a plus terminal, which can be a safety hazard. Also the metal chassis is not connected with a safety ground. So the device does not meet the Low Voltage Directive for a CE mark, and needs to be used with care (or modified, which is not difficult). Overall, a good product.
