Structural Features Standard TDC 3000 plug-in power supply module form factor. Front panel integrates AC input terminal, status LED indicators and extraction handle. Internal layout separates high voltage AC input zone and low voltage DC output zone with insulation barrier. Built-in aluminum heat sink dissipates heat from power switching components. Anti-key notch prevents reverse insertion into rack slot. Locking clip secures module firmly after installation. Internal shielding reduces switching noise interference to adjacent control cards.
Working Principle AC input power enters through front terminal block and passes input surge filter circuit. High frequency switching circuit converts AC into isolated DC voltage. Regulation circuit maintains stable 5VDC and 12VDC output for backplane bus. When load current exceeds rated value or short circuit occurs, current limiting circuit cuts off output. When internal temperature exceeds threshold, thermal protection circuit triggers shutdown. In redundant configuration, two power modules share load equally. If one module fails, the second module takes over full rack power supply without interruption.
Installation Requirements Cut off upstream AC power before installation. Wear anti-static wrist strap. Insert module into dedicated power slot of TDC 3000 rack and lock extraction handle. Connect AC power cable to input terminal block and complete protective earth grounding. Configure redundant power mode in TDC 3000 engineering software. Restore AC power and verify DC output LED status. Test single power supply failure by disconnecting one AC input in redundant rack. Verify all rack modules keep online during test.
Usage Notes Do not connect input voltage beyond 120/240VAC rated range. Keep ventilation space around power module heat sink. Clean dust on heat sink periodically to prevent over temperature. Do not remove protective earth wire. Do not replace internal capacitor or power components by unauthorized personnel.
