Undervoltage Switch works fine, but terminals are too small for 20A (2.5mm2) wiring. Weird as internal relay is Normally Closed and unit draws 54mA when output enabled and 95mA when disabled I.e. it draws more on undervoltage trip when the battery should be conserved. Instructions mistakenly state "Overvoltage setting", should be termed "Recovery or re-enable" voltage setting as output is reinstated once the value is exceeded.

Good product. Description of output requires attention. Relay can be destroyed if voltage spike from relay coils connected to output terminals. In such instance free wheeling diodes must be placed across any inductive load (relay coil)

Hi,it was ok until yeasterday when it stoped,and is dead ,no output . I used it with a 250W solar panel to control the battery voltage of a cooling box (no compressor) that draws 6A when in use.
