SCR ELEKTRONIKS have developed ‘PC BASED TEST SETUP FOR FUSES AS PER IEC 60269’ to cover most of the tests for fuses recommended by various national & international standards such as IEC,UL, BIS & so on. It has all the facilities to conduct the following tests for fuses as per IEC 60269-1:   Features   1 CURRENT TRANSFORMER RANGES: CT1: 2A,5A,10A,20A,50A,100A,200A CT2: 500 A,1KA, 2KA, 4KA, 10KA, 20KA, 40KA 2. VOLTAGE TRANSFORMER RANGE: 5V,10V, 20V voltage tap selection. (Newly introduced) 35V,40V, 50V 6. MODE OF OPERATION: Manual Mode Timer Mode (Auto Mode) PC Mode 3. RANGE SELECTION: Through contactors. Manual Mode and Auto Mode (Timer Mode) – With switches. PC Mode – CT range is selected through PC with the help of relays and contactors. 4. INDICATIONS: Current on digital Ammeter (on servo controller unit), True RMS based with class 1 accuracy. Time on auto ranging microcontroller based Timer, between 1msec – 999 min. Transient current displayed on Digital Transient Recording Meter with class 1 accuracy. Digital Temperature Indication 6 channels: 3 ½ digit for Cr/Al (K type) thermocouples are used as sensors with accuracy of 1 % +/- 1º C Temperature sensing with isolated transmitters to avoid short circuit. 5. Micro Controller based unit (PROGRAMMABLE TIMER) controls the sequence of operation and measures time with 1 msec resolution. 10. Elegant housing with Aluminum profile and front panel control with self explanatory nomenclature. 11. IN PC MODE: Test selection, Range selection complete sequence of operation and data logging through NI DAQ unit and LABVIEW software. 12. OUTPUT TERMINALS: On heavy duty bus bars. (5V,10 V, 20V) 13. Two separate modules mounted on castor wheels. oil cool variac power module   Specification INPUT SUPPLY : 400 V, 3 phase, 50 HZ /100 A continuous. 2000 A for short time minimum voltage 380V OUTPUT CURRENT : 2A to 3500A/20 V continuous. 3500A to 35000A short time (2 sec)

The module has arrangement for fuses of 4U spaces vertically in a standard 19 inch rack • System operates with N+2 wires • Continuously monitoring the status of both Main and Spare fuse • Automatically changeover to a Spare Fuse on failure of the Main Fuse in less than 20 msec • Current drain from the main system is very low • Provides audiovisual alarm on failure of any fuse • Push button to test whether all indications are working • The audio alarm is resettable by push button • Operating Voltage: 24VDC or 60VDC or 110V AC • Fuses confirming IEC-127 • Each PCB coated with Acrylic coating which prevents components from moisture
