Additional information:

Measurement and regulation.

The power supply required by the module should be between 5 and 5.1V. The module has voltage measuring points -

described: VCC and GND. They are used to measure voltage under load. They can facilitate fine adjustment of the power

supply (if the power supply has such a possibility).

Socket polarization:

Specification.



supply voltage: 5V DC



power supply current: min 2A



built-in 3A fuse



short-circuit and overload protection: ≥ 6V



reverse polarity protection



LEDs indicating module operation (upper: control voltage, lower: main voltage)

The "U2" part is a fuse. It is part of the security features and is a replaceable part (spare part attached to the manual).

Blowing the fuse is deliberate to protect the device and its replacement is not covered by the warranty. It may act due

to incorrect power supply voltage or connection.

If necessary, a replacement with the following parameters can be used:



type of operation: fast-acting fuse



housing SMD - 1206



voltage 32V, maximum allowed 63V



fuse current 3A



maximum allowed resistance: 30 mOhm (0.03 Ohm)



maximum allowed voltage drop: 90 mV (0.09 V) at 3A current
