Gnd – This is the return pin for the Input control voltage. +OUTPUT – This is the positive terminal of the “contact”. -OUTPUT – this is the return terminal for the +OUTPUT pin. Note: 1. Input pins and output pins are isolated up to 2000VDC 2. The device may be damaged if the input polarity is reversed. 3. The “contact” is uni-polar, a voltage reversal will result in current flow in the internal diode.

Input Bias The SSR050D060 will be energized and the “Contact” will be closed, when a positive potential of 4.6VDC to 36VDC is applied between Input and Gnd. The input power consumption will be constant through out the control voltage range therefore the contactor will draw more current at lower control voltages.

Output Load Connection The output circuit is completely floating therefore the Load can be connected to either output terminal. Load connected to +Output Terminal Load Connected to –Output Terminal C. Over Current Disable The SSR050D060 contains an Over Current latch which disables (opens) the contact whenever a large current in excess of 400A is detected. The latch can only be reset be removing and reapplying the input control power. In noisy environments and in applications where high surge currents are encountered, the latch may be triggered prematurely. In these applications the latch circuit can be disabled by placing a short circuit between the over current disable terminals. • 221 West Industry Court Deer Park, NY 11729 (631) 586 7600, FAX 631 242 9798 • • World Wide Web - www.sensitron.com • E-mail Address - [email protected] • Page 7 SENSITRON SEMICONDUCTOR SSR050D060 TECHNICAL DATA DATASHEET 5063, REV. - D. Contact Protection The user must insure that the peak voltage rating of the SSR050D060 is not exceeded. The SSRXXDXXX family of devices switch at extremely fast speeds, therefore extra care must be taken to suppress voltage transients that are generated when interrupting high currents. Sensitron strongly advises the user to us a snubber network similar in design to the one shown below. This is an energy absorbing snubber that transfers the energy from any parasitic line inductance into the capacitor and then is dissipated through the resistor. The capacitor should be sized so that the captured energy does not charge the capacitor beyond the contacts rated voltage. E. AC Operation The contactor can be used for AC loads if two devices are connected “back to back”. • 221 West Industry Court Deer Park, NY 11729 (631) 586 7600, FAX 631 242 9798 • • World Wide Web - www.sensitron.com • E-mail Address - [email protected] • Page 8 SENSITRON SEMICONDUCTOR SSR050D060 TECHNICAL DATA DATASHEET 5063, REV. - DISCLAIMER: 1- The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
