Components Eltek Valere Debuts New -48 VDC Battery Distribution Fuse Bay Cole Hersee Introduces the FlexMod Voltage Sensing Relay and Timer Cole Hersee introduces the Voltage Sensing Relay and Timer (VSRT), a new product in the FlexMod line. The FlexMod VSRT conserves the starting power of a vehicle battery by shutting off auxiliary loads when either starting voltage drops to a low level, or a pre-set timer times out. The FlexMod VSRT is well suited for utility and fleet vehicles, as it virtually eliminates the possibility of vehicles not starting due to a dead battery. This small (4 inch by 3 inch by 1 inch) piece of equipment alerts the vehicle operator when starting voltage is low and then temporarily cuts off any nonessential electrical loads, thus conserving power to start. Cole Hersee utilizes solid state technology in the creation of the FlexMod VSRT, providing long life and zero maintenance or replacement. Its service life exceeds 1,000,000 on/off cycles, operating for the entire lifetime of the vehicle. This device has a rating of 10 A, and can handle many loads directly or drive a relay or solenoid for higher amperages. Eltek Valere has debuted its 48 VDC battery distribution fuse bay (BDFB). This versatile, advanced-function distribution bay ensures a continuous power supply for large telecom networks and wireless mobile telephone switching offices (MTSOs). The 48 VDC BDFB provides a variety of load busses and fuse options; it can be configured as a single bus bay or equipped with up to six separate load busses, depending upon the desired configuration. Both fuses and circuit breakers are accommodated. The BDFB has a capacity of 600 A per bus at -48 V, delivering a maximum total current capacity of 3,600 A. Monitoring and control of the BDFB is crucial for high reliability and availability, as well as for performing periodic maintenance operations. At the heart of the BDFB is Eltek Valere’s Smartpack2 controller, which offers remote and local access to system data; programmable settings and alarming; and monitoring. The color display panel shows load voltage and current on each bus. In addition to standard alarms, the Smartpack2 controller’s extensive programming capabilities allow for custom alarm threshold values, alarm grouping and more via both remote and local access. The BDFB comes with two, four or six input feeds, each equipped with 800-amp shunts. It is designed to meet or exceed NEBS, UL and CSA requirements.
