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