NOTES [1] The accuracy specification applies for any combination of operating temperature and voltage. [2] The accuracy will not be affected by power interruptions up to 1 millisecond, spaced at least 10 milliseconds apart. Transient and power loss specifications are based on a maximum duty cycle of 1/50. [3] EMI test limits will not be exceeded during the timing interval or when continuously energized under steady state conditions, per paragraph 3.23, MIL-PRF-83726C. [4] Terminals X1, X2, A1, B1 and A3 must be connected together during the test. Dielectric withstanding voltage and insulation resistance are measured at sea level between all mutually insulated terminals and between all terminals and case. [5] Recycle time is defined as the minimum time control power must be removed from terminal B1 to assure that a new cycle can be completed within the specified timing tolerance. [6] A four digit number defines the time delay in seconds (or milliseconds). The first three digits are significant figures, used to define the specific time delay. The fourth digit represents the number of zeros to follow the first three digits. Examples: - 1001 = 1 second (1,000 milliseconds) - 2502 = 25 seconds (25,000 milliseconds) - 5000 = 0.5 seconds (500 milliseconds) [7] Quality level as specified in MIL-R-83726, paragraph 3.1.1, 3.1.2 and 3.1.3. Date of issue: 3/06 - 75 - Page 3 of 3 N101 Application notes DERATING OF CONTACTS FOR DC VOLTAGES ABOVE NOMINAL RATING To establish a standard for the derating of relay contacts is, at best, a subjective practice. Limitations are governed by the type of relay, contact gap, maximum voltage capabilities of the relay contact system, and the contact material. The most common method is to derate the contacts by use of the Power Formula, using the known current and voltage. This method is valid only for Resistive Loads, and is an approximation only; keeping in mind the limitations mentioned above. Power = IE (Current x Voltage) I2 E2 = 2/3 I1E1 Example: A designer is working with a 55 volt DC system and has a relay rated at 10 amps resistive at 28 volts DC. What is the maximum current that can be switched at 55 Vdc. I1 = 10 Amperes E1 = 28 VDC E2 = 55 VDC I2 = ? (Current ratings at 55 VDC Resistive) I2 E2 = 2 I1 E1/3 I2 = 2 I1 E1/E23 = 2 (10 x 28)/55 x 3 = 560/165 I2 = 3.4 Amperes at 55VDC In addition, the user should always be concerned about the following: 1. Derating contacts that are rated for less than 10 Amperes at nominal voltage. 2. Derating contacts for use in system voltages above 130 Volts DC Date of issue: 6/00 - 14 - Page 1 of 1 SM-1000-003 ENGINEERING DATA SHEET TRACK MOUNT RELAY SOCKET 5 AMP BASIC SOCKET SERIES DESIGNATION FOR: Series X (Track Mount) Series TD-1609, TD-1610 (Track Mount) DESIGNED TO THE STANDARDS AND REQUIREMENTS OF: MIL-S-12883/52 APPLICABLE TRACK: MT-3000-03 GENERAL CHARACTERISTICS 1.
