Rack mounting, dual-circuit, power supply, or booster
The Tecpro PS754 provides two channels of 24V DC system power for Tecpro intercom systems and has two modes of operation. It may be used as either the principal system power supply for a system, when it terminates the audio lines with the correct impedance, or to boost system power where the existing power supply is underpowered, where termination is not required.
Features
Compact 1U format
Single male XLR3 and female XLR3 connector per circuit for cable loop-through
Universal power supply
Short-circuit and overload protection with indication on each intercom circuit
Compatible with previous generation Tecpro designs
In 'Power Supply' mode, it provides two independent intercom circuits each rated at 1.1A each. This is sufficient to power 22 BP511 belt-packs per circuit. Circuit B can be linked to circuit A to provide a single 'super' circuit. The link switch is recessed in the front panel to avoid accidental operation. A 'Link' LED indicator is provided. On the rear, two pairs of male and female XLR connectors are wired in parallel, one pair for each of the two circuits. Switching from 'Power Supply' mode to 'Power Boost' disables the audio termination on circuits A and B. The rear-mounted mode switch is recessed to avoid accidental operation. When 'Power Boost' mode is selected a 'Termination Off' LED illuminates on the front panel.
Circuits A and B have dedicated power supplies with short-circuit protection. Protection is electronic and automatic and no resetting is necessary following the removal of a fault condition. As the supplies are independent, in the event of a cable fault temporarily disabling one circuit, the other circuit will continue to operate uninterrupted. When a fault is registered, the 'Overload' LED for that circuit will illuminate until the condition is removed.
