Application circuit
External components setting
FUSE: Fuse Please make sure to use quick acting fuse 2A
Capacitance : 47mF to 220mF Rated voltage : 200V or higher
Ripple current is 0.22Arms above.
C1: Capacitor for input
voltage smoothing
Capacitance : 0.1mF to 0.22µF Rated voltage : 200V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
C2: For noise terminal
voltage reduction
Capacitance : 330mF to 1000µF Rated voltage : 25V or higher,
ESR is 0.08 max. Ripple current is 1Arms above.
Output noise voltage is influenced,Please evaluate it in the actual set.
C3: Capacitor for Output
voltage smooting
Please use the first recovery diode that reverse peak voltage is 400V or
higher, and the avarage rectifying current is 3A or higher.That switching
characteristic and efficiency of our module is influenced by this diode
characteristic, please use 31DF4(Nihon inter), or RV30(Sanken).
D1: Flywheel diode
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 1A or higher,
and the peak surge current should be 20A or higher.
(Full-wave rectifier can be used in our part.)
D2: Rectifier diode
1.0 to 2.2 1/4W
Reduce the noise terminal voltage.The constant value should be evaluated
in set.
R1: For noise terminal
voltage reduction
Coil for switching regulator. The inductance should be 470mH,
the rated direct current should be 1.6A above. Otherwise heating or
abnormal oscilation occurs.
L1: Choke coil
Varistor must be used. It protects this part from lightning surge and static
electricity.
ZNR: Varistor
For acutual usage, Please kindly evaluate and confirm our part mounted in your product,
Especially, Please make sure to confirm the load current does not exceed Max. rated current
by using the current probe.
