Power supply

The variant DHS is designed for operation with a DC (18 V to 72 V, DC-insulation

1.5 kV). The voltage feed is done through 3 pol DFK connector in the front panel of

the clock and should have low resistance to minimize spurious emission (EMI).

The type AHS with an AC (100 V to 240 V, 47 Hz to 63 Hz) and also DC (100 V

to 240 V DC) power supply. The special model DAHS provides 3 pol DFK connector

in the front panel instead of power cord receptacle. Both includes a fuse T500 mA

which is available inside the housing.

To avoid potential differences between the signal ground of AHS/DHS and a post-

connected unit installed on different DIN rails, the signal ground of the clock is

insulated from the case.

The case must be grounded by using the rear contact!
