SUCW1R5xx12/SUCW1R5xx15 is available as single output, +24V/+30V. Rated input 5V, 12V, 24V or 48V DC Io=100% Ripple and Ripple Noise is measured by using measuring board with capacitor with in 25mm from output terminal. Drift is the change in DC output for an eight hour period after a half-hour warm-up at 25C. Parallel operation with other model is not possible.

2.3 Isolation
For a receiving inspection, such as Hi-Pot test, gradually increase (decrease) the voltage for the start (shut down). Avoid using HiPot tester with the timer because it may generate voltage a few times higher than the applied voltage, at ON/OFF of a timer.

2.4 Adjustable voltage range
The output voltage is adjustable by external potentiometer (Refer to Table 2.1). Output voltage is increased by turning potentiometer clockwise and is decreased by turning potentiometer counterclockwise. The wiring to the potentiometer should be as short as possible. The temperature coefficient varies depending on the type of resistor and potentiometer. It is recommended that the following types be used. Resistor.................Metal film type. coefficient of less than t300ppm/C Potentiometer........Cermet type, coefficient of less than t100ppm/C When the output voltage adjustment is not used, open the TRM pin. Dual output is simultaneously adjustment of t.

3 Wiring to Input/Output Pin
Basically, SU / SUC series do not require any external capacitor. However, as pi filter is composed by connecting capacitor:Ci close to the input pin, reflected input noise from converter can be reduced. It is recommended to use high performance (temperature compensation and high frequency characteristics) capacitor. If abnormal voltage like a high surge is applied to the input side, Ci is effective to reduce its level. However, Ci life time should be considered. When the external filter which contains L(inductance) is installed on input line, or the length of wire from input source to converter is greatly long, the reflected input noise might be increased, the input voltage might get several times higher than a normal level

6.4 Cleaning
When cleaning is necessary, follow the undermentioned condition. Method: Varnishing, ultrasonic wave and vapor Cleaning agents: IPA (Solvent type) Total time: 2 minutes or less After cleaning, dry them enough. In case of ultrasonic wave cleaning, the ultrasonic should be less than 15kw/m3
6 Implementation-Mounting Method
6.1 Installation method
The unit can be mounted in any direction. Position them with proper intervals to allow enough air ventilation. Ambient temperature around each power supply should not exceed the temperature range shown in derating curve. Avoid placing pattern layout in hatched area in Fig.6.1 to insulate between pattern and power supply.

7 Safety Considerations
To apply for safety standard approval using this power supply, the following conditions must be met. This unit must be used as a component of the end-use equipment. The equipment does neither contain any basic nor double / reinforced insulation between input and output. If the input voltage is greater than 60VDC, this has to be provided by the end-use equipment according to the final build in condition.

6.2 Automatic mounting
SU/SUC series (TYPE:B) is designed to have a large flat area in the center of the top surface to serve as a pick up point for automated vacuum pick and place equipment. An excessively low bottom dead point of the suction nozzle imposes great force on the core during mounting, causing cracked core. So during mounting, take enough care. Refer to External view.
6.3 Input/Output Pin
www..com When too much stress is applied on the input/output pins of the unit, the internal connection may be weakened. As below Fig. 6.2, avoid applying stress of more than 19.6N (2kgf) vertically. The input/output pins are soldered on PCB internally, therefore, do not pull or bend them with abnormal forces. When additional stress is expected to be put on the input/output pins because of vibration or impacts, fix the unit on PCB (using silicone rubber or fixing fittings) to reduce the stress onto the input/output pins.
