The input - All of the VWRBS2-SIP Series have been tested current of the power supply must be sufficient according to the following recommended testing to the startup current (Ip) of the DC/DC module circuit before leaving the factory. This series should (Figure 2) be tested under load(Figure 1). If you want to further Input Current(A) decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high(Table 2).

No parallel connection or plug and play. Temperature Derating Graph - NC Terminals Unless otherwise specified, NC terminals of all series are used for converter's interior circuit connection, and are not allowed connection of any external circuit.; Operating Temp.( C ) - Remote on/off control (see figure 1) ON: When control pin (CTRL pin 3) open or Ic < 0.5mA, converter will have normal output. OFF: With a 3-10mA input current (Ic) to pin 3, output will be disabled. Under no conditions should input current (Ic) exceed 20mA. The Value of R in Figure 1 can be derived as follows: R= Vc - Vd - 0.65V Ic Vc= Voltage at control input Vd= Diode (D1) voltage drop (.7V voltage drop typical ) Ic= Input Current (5mA recommended disable current) example 1 : Logic circuit — Apply 5V TTL logic signal on Vc to disable output R= 5V - 0.7V - 0.65V = 730 Ω .005A Choose 720Ω resistor example 2 : Short Vin to Vc — Apply 12V on Vc to disable output R= 12V - 0.7V - 0.65V = 2130 Ω .005A Choose 2K Ω resistor 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2382
