10 / 10 page SENSITRON SEMICONDUCTOR TECHNICAL DATA DATASHEET 5065, A • 221 West Industry Court Deer Park, NY 11729-4681 Phone (631) 586 7600 Fax (631) 242 9798 • • World Wide Web - http://www.sensitron.com • E-Mail Address - sales@sensitron.com • Page 10 SPDP50D375-503 The 9-pin D-Sub connector DSUB1 is used for control; we recommend using a standard cable of no more than 3 ft. This will ensure that the noise and other interference are kept to a minimum. The DSUB2 is used for setting the current levels and instant trip levels. We expect the customer to configure this connector locally; any cables attached to this connector may cause nuisance trip or malfunction of the unit since the internal control points are brought out of the pins. As a general rule, current-carrying power circuit should be kept well away from the control circuit and other low-level circuits in the system. It’s unlikely, but possible, that magnetic coupling could affect the control circuit when turning normal loads on and off. However, in the case of an overload, the magnetic coupling could be 10 times greater than with normal loads. Effects of such coupling could cause ‘chattering’ when turning on and off, oscillation, and the possibility of turning the SPDP50D375 back on after an overload. The SPDP50D375 Series is a Trip-Free device. Once tripped it will not turn back on until reset and commanded on again. Reset is accomplished by bringing the “CONTROL” pin low and turning the SSPC back on is accomplished by bringing the “CONTROL” pin high. Sufficient magnetic coupling between the current- carrying power circuit and the control circuit can negate the Trip-Free characteristic. MIL-STD-704F This standard covers the characteristics of the electrical systems in Military Aircraft. The SPDP50D375 Series meets all of the requirements of MIL-STD-704F including Normal, Emergency, Abnormal and Electric Starting conditions with the Ripple, Distortion Factor and Distortion Spectrum defined in the standard. In addition, the SPDP50D375 Series can withstand + 600 V spikes for 10µS. This capability is beyond that required by MIL- STD-704F.
