Part Number: PMS610 – 24
Title: 24 VDC Power Supply & Mainframe (-24VDC out)
Category: PMS Mainframe
Industry: TV/Radio Broadcast, CATV Cable Industry
The versatile PMS610 Mainframe/Power Supply features the unique capability of housing and powering any combination of the System 600 Stereo Processors that add up to three card spaces in a 1.75″ H x 19″ W rack. Sophisticated design and low power consumption result in smaller modules that can be closely packed together without overheating, thus providing more programming services per headend space. Most FM Systems System 600 modules occupy one card space, although some modules (typically those with ad insertion capability) occupy two card spaces. Thus, the PMS610 Mainframe system can potentially supply up to nine stereo program services in the same headend space as a 5.25″ H x 19″ W card cage. This lightweight and durable aluminum Mainframe is also fully enclosed to provide excellent shielding from RF fields and to prevent internal signals from interfering with nearby equipment. Individual modules are easily installed and/or removed through the bottom cover plate.
The power supply delivers regulated -24 volts DC from a 115VAC power source. A green LED on the front panel indicates a ‘power-on condition. The AC power line is protected from overload by a re-settable circuit breaker on the rear panel. This circuit breaker is not a switch, thus power cannot be removed accidentally. The solid state voltage regulator is also fully protected from accidental short circuits. Additional features ensure safe ‘power-down’ in the event of component failure or overheating due to external causes.
For the operator’s convenience, front and rear panel designation labels are provided with the equipment cards. The universal front panel pattern permits any card to be placed in any location. Blank designation panels for all unused card spaces ensure uniform appearance.
