DC 24V

A figure displayed with the AC or DC before the value represents a nominal voltage with

standard tolerances included.

E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)

24Vdc

A figure with the unit (Vac) at the end is a momentary figure without any additional

tolerances included.

Mar. 2016 / Rev. 1.3 DS-CD5.243-EN

All parameters are specified at 24V, 4A, 12Vdc input voltage, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
