NAME DESCRIPTION OR FUNCTION Control With a jumper between these terminals and the battery connected, the TBC Con- trol Board will remain ON even if the AC Circuit Breaker is OFF. With the jumper ON/OFF removed the Control Board will go OFF if the AC Circuit Breaker is OFF.

  • Page 14: Ac Source Power Requirements

    FIGURE 2-3. TBC REAR PANEL AC SOURCE POWER REQUIREMENTS The TBC Battery Charger Power Supply is supplied for operation on a single phase line with a-c input voltage between 100V and 250V a-c nominal (universal a-c input). The circuit breaker remains effective at all input voltages.

  • Page 15: Cooling

    FIGURE 2-4. AC INPUT POWER TERMINAL BLOCK, TB3 COOLING The power transistors and rectifiers in the TBC Battery Charger Power Supply are maintained within their operating temperature range by means of special heat sink assemblies, cooled by internal fans. CAUTION: SIDE PANEL OPENINGS AND THE TOP OF THE CASE MUST BE KEPT CLEAR FROM OBSTRUCTIONS TO ENSURE PROPER AIR CIRCULATION.

  • Page 16: Rack Panel Mounting

    To release the circuit breaker locking plate loosen the two knurled head screws (6-32 x 1/2) and slide the locking plate to the right (see Figure 2-5A). For models TBC 24-120M and TBC 48-60M slide the locking plate down (see Figure 2-5B). FIGURE 2-5.

  • Page 19: Section 3 - Operating Instructions

    SECTION 3 - OPERATING INSTRUCTIONS GENERAL Interconnections between a stabilized Battery Charger Power Supply, and its load are as critical as the interface between other types of electronic equipment. If optimum performance is expected, certain rules for the interconnections must be observed by the user. These rules are described in detail in the following paragraphs.

  • Page 20: Load Connection, Method 2 (Remote Error Sensing)

    FIGURE 3-1. LOCAL ERROR SENSING CONNECTIONS LOAD CONNECTION, METHOD 2 (REMOTE ERROR SENSING) To avoid excessive output effects at remote loads, remote error sensing must be used. The links between the +S and + M terminals and between the -S and -M terminals must be removed. Use a twisted, shielded pair of wires from the Sensing Terminals directly to the load to compensate for load wire voltage drops.

  • Page 21: Parallel Operation

    FIGURE 3-2. REMOTE ERROR SENSING CONNECTIONS PARALLEL OPERATION Up to three identical TBC Battery Charger Power Supplies can be connected in parallel opera- tion, except for models TBC 48-60M and TBC 24-120M, which have two power supplies in par- allel that are built into the units. For the TBC 48-60M or TBC 24-120M only one additional TBC unit can be connected in parallel.
