Benet
A combination of Model ACTP250J1BJR-S
and an MOV reduces the stress on diodes
and capacitors compared with a single
MOV of equal voltage rating. Does
not compromise MOV clamping. No
degradation of leakage current over time.
Small form factor.
Objective
Metal Oxide Varistors provide protection for o
line power converters from dierential surges (2 Ω
impedance) of greater than 2 kV. ey clamp the
incoming transient and reduce the peak current
which stresses the diodes and bulk capacitor. Model
ACTP250J1BJR-S is an SMB package device which
can add an extra 135 Vrms to the rated voltage of the
surge protection when placed in series with the MOV.
is does not compromise the clamping voltage of
the MOV. is is a solution for applications where
swells in the AC voltage occur or where a reduction
in surge current in the bulk capacitor is desired.
For low power (less than 20 W), a UL listed fusible
wirewound resistor, Model FW30A10R0JA, helps
to attenuate surges and inrush currents as well as
providing fuse protection from diodes shorting. For
peak surge currents higher than 1K A, the Model
ACTP250J1BJR-S should be replaced by a gas
discharge tube such as the SA2 series.
