Description

The U 210 B is fitted with voltage limiting and can therefore be supplied directly from the mains. The supply voltage
between Pin 2 (+pol/) and Pin 3 builds up across D1 and R1 and is smoothed by C1. The vaIue of the series resistance can be approximated using:
           VMVS
R1  = ------
             2 IS
Further information regarding the design of the mains supply can be found in the data sheets in the appendix. The reference voltage source on Pin 13 of typ. 8.9 V is derived from the supply voltage. It represents the reference level of the control unit. Operating using an externally stabiIised DC voltage is not recommended.

If the supply cannot be taken directly from the mains because the power dissipation in R1 would be too large, then the circuit U 210 B shown in the following Figure 3 should be employed.
