Pro Intercom PS3 24VDC XLR Battery Operated Power Supply

The Pro Intercom PS3 is a high-quality 24VDC XLR Battery Operated Power Supply that is designed to provide reliable power for your audio equipment. The PS3 provides the facilities necessary to power your cabled intercom system from batteries. Typically, a pair of 12V batteries are wired in series to provide 24V, then connected to the PS3. Best because of size, weight, and recharge-ability, are computer UPS or motorcycle batteries, but auto or even lantern batteries may be used. Time between recharging will depend upon the number of stations connected, but as an example, a pair of 150 Ampere/Hour batteries would power ten belt packs, with their signal lights constantly On, for over 1000 hours.

Key Features

• The PS3 allows you to operate a moderately large intercom system from batteries
• Connect two 12V rechargeable batteries (typically those used in a computer Uninterruptable Power Supply or a motorcycle) in series to achieve 24VDC and connect them to the front panel terminals
• The three XLR outputs on the back are in series (one circuit), Batteries are NOT provided
• The PS3 also provides the 200 Ohm termination point for the intercom audio
• The most important feature of the PS3 is the Swiss-made, very fast circuit breaker on the front panel
