Especially, Please make sure to confirm whether the load current exceed Max. rated current
by using the current probe.
External components setting
FUSE: FUSE
Recommend the use of fast-acting type fuse 1.0A.
C1: Input capacitor
Rated voltage : More than 250V
Capacity : 22 to 100µF
C2: Output capacitor
Rated voltage : More than 25V
Capacity : 100 to 470µF, low impedance type
ESR : Less than 0.16Ω
Rated ripple current : More than 0.58Arms
Evaluate it with the actual opportunity because it influences
an output ripple voltage.
C3: Noise removal capacitor Rated voltage : More than 250V
film capacitor, or Ceramic capacitor
Capacity : 0.1 to 0.22µF
L1: Choke coil
Inductance : 820µH
Rated current : More than 0.42A.
Choose components that do not easily get magnetically saturated
in high temperature.
R1: Noise removal resistor Resistance : 10 to 22Ω
Power : More than 1/4W
D1: Rectifier diode
Peak reverse voltage : More than 400V
Mean rectifying current : More than 1.0A
Peak forward surge current : More than 20A
This product can use even all the wave rectification.
ZNR: Varistor
Be sure to use it to protect this product from thunder surge and the static
electricity.
