The SWB Series features Sanken' s proprietary resonant-mode power hybrid
IC and transformer. These models provide the high efficiency and low noise
that can only be realized with a resonant-mode supply. These supplies can
accept an input voltage range of 85 to 264 V, and feature continuous input
operation which requires no manual voltage selection. Their design makes it
easy to meet the power supply needs of world-wide applications.

Note 1: At cold start. (More current may flow at restart.)
Note 2: Ripple noise is measured with a 100 MHz oscilloscope, using a 1:1 probe.
Note 3: Output characteristics are measured at the output connector. Ripple noise is measured at a point 5 cm from the output connector, with a 63 V 47 F
electrolytic capacitor attached at that point.
* "Rated input/output conditions" means that the switching power supply is operated under the rated input voltage, rated output voltage, rated output
current, rated frequency, and at an ambient temperature of 25C and 60% humidity.

Operating instruction (SWB Series)
1 Setting the output current
Output current may be adjusted using the adjustment knob
found near the connector or terminal base. Turning the knob
clockwise increases output current, while turning it
counterclockwise decreases output current. Use the power
supply with the output within its adjustable range and with a
load such that the supply's rated output power is not
exceeded.
2 Overcurrent protection
When the output is overloaded, the power supply's built-in
overcurrent protection will shut off the output. The
overcurrent protection is set to function when the output
current exceeds 105% of the rated current value (about 130%
of a standard output value).
To reset the overcurrent protection, remove the source of the
overload, turn off the power, and wait about a minute before
turning the power on again.
3 Overvoltage protection
If the output voltage increases for some reason, the
overvoltage condition is detected and the output shut off.
Once the overvoltage protection is activated, the output will
remain cut off as long as the input supply is energized. To
reset the overvoltage protection, turn off the power and wait
about a minute before turning the power on again.
Take care when applying power again, as there may still be a
problem with the output voltage (if there is, the overvoltage
protection will shut down the output again).
4 Mounting
To use the power supply with natural air cooling, mount the
supply so that both sides and the top are open, and so that
there is sufficient air current.
The power supply may be mounted either vertically or
horizontally, as shown below. Use mounting screws that are
5 mm long or less.
