11.1 Transformer
11.1.1
The transformers are available either loose or installed in a sheet metal housing. When in-
stalling in the control cabinet, it is essential to make allowance for the heat dissipated from
the transformers. The control cabinet may have to be provided with forced-air cooling.
11.1.2
A single large transformer may be selected to serve several humidifiers. In such cases,
make sure that each outgoing secondary circuit is fuse-protected, either external in the
control cabinet or within the transformer ex- factory.
11.1.3
The transformer transforms the primary voltage of 230 V / 50 Hz to the secondary voltage
of 48 / 53 V.
11.1.4
The power connection cable leading to the transformer and from the transformer to the
humidifier must at least satisfy H05VV or H05RR specifications.
11.1.5
The transformers of BOGA are manufactured according to the following specifications:
Single-phase control-power transformer in accordance with VDE 0550 Parts 1+3 and VDE
0113, IP00, Protection Class 1, Insulation Class T40E, separate windings, screw-
connection in accordance with VBG4, 50/60 Hz.
