The PS301 is the ideal combination of analog/linear and digital circuitry. The supply section is linear with a toroidal transformer coupled with linear regulators to virtually eliminate stray-field radiation. The PS301 will play well with other sensitive audio and lighting gear with which it shares rack space.
The performance of the power supply is extensively monitored by a microprocessor which detects heat, voltage and the status of both the input and output. Each of the three circuits is monitored independently and faults are reported to the front panel. A red LED indicates when there is a problem with each circuit by flashing. If the fault requires shutting down the circuit, the LED lights steadily. The circuit resets when the fault is removed without booting the power supply.
The power supply provides power for up to 66 beltpacks connected to the circuits. Power is well regulated at 24 volts DC and will automatically adjust down during periods of line voltage brownout or high loading with speaker stations or other equipment.
Short circuit protection and current limiting prevent component damage in the event of connection error or cable failure.
The PS301 has a quiet built-in fan that turns on automatically when needed to cool the unit.
Each circuit has a characteristic impedance of 200 ohms at audio frequencies, allowing many beltpacks to be connected together without significantly changing the circuit performance.
The circuits may be linked in A+B or A+B+C configurations via a front panel switch. The termination networks are automatically removed and inserted during circuit linking to ensure a constant impedance for all circuits.
The termination networks may also be manually removed by setting a switch on the rear panel, if desired. This may be useful when using an adjunct network, or if interfacing with a larger communications system.
The PS301 has a program input which can be directed to any or all of the three circuits. Each circuit has an LED VU meter to report to the operator the level being sent to that circuit, and a control to regulate it.
The PS301 will operate in either the 120VAC or 240VAC range. Selection and correct fusing are done on the rear panel. The power inlet is IEC and we supply power cords with the correct plug for most of the world’s electrical outlets.

eventag - Mieten oder Kaufen von Veranstaltungstechnik1. The PS301 is a 3circuit Power Supply with a unique hybrid configuration. Microprocessors operate all the switching, routing, and supervision functions, while the audio paths and the core power supply remain analog. The result is a station with unrivaled flexibility, muscular reliability, and clean, smooth audio.
2. The PS301, as in all the 300 series master stations and power supplies, has a large toroidal transformer whichgives off virtually no strayfield radiation to interfere with the other devices with which it shares rack space.
3. Those power supply components which create heat are mounted on a massive heat sink, and, when necessary (rarely) get extra cooling from a thermally regulated cooling fan.
4. Each of the 3 PS301 circuits is independent of the others, except for sharing the toroidal transformer and the rectifier. Therefore, a problem on one circuit does not affect the others. When a circuit problem occurs, and is eliminated, the PS301 resumes normal operation without rebooting.
5. The monitoring and control functions include automatic adjustment of the termination impedance when the circuits are combined, adjusting to brownouts or sudden drops in line voltage, monitoring the temperature of theheat sink and switching the cooling fan on when required, and reporting the status of each circuit to LED indicatorson the front panel. The top, green LED reports that 24VDC is being delivered to the system. The lower 3 LEDs are green when that circuit OK, and become red when it is experiencing an overload and or short circuit and therefore has been shut down until the problem is solved.
6. The transformer has primary windings for both 120VAC and 240VAC (50/60 Hz) and allows wide deviation fromthose voltages without any effect on performance. At as low as 100VAC, the secondary voltage will remain at24VDC while the available current will be slightly reduced from 2.4A continuous to 2.0A continuous. The voltage and fuse are changed on the rear panel.
7. The components and microprocessor which monitor and adjust the power supply’s performance are separatelymounted on their own circuit board, as far as possible from any heat source.
8. The PS301 can be used with any unbalanced 200 Ohm partyline intercom components.
9. Each circuit has a DIP switch on the rear panel for lifting the termination circuit. This is only needed when the
PS301 is augmenting a system which already has a termination circuit.
10. There are 3 DIP switches on the rear panel for lifting the termination circuits. This is only necessary when the
PS301 is being used to augment a system which already has a termination circuit.
