User manual ART PS8 PRO

[. . . ] (4. 4kg) OPERATION POWER SWITCH The PS8 PRO has a master POWER switch for the rear outlets. This switch glows when the unit is enabled. If the rear REMOTE is not being used, turning on this switch initiates a power on sequence for the rear outlets. Turning off the switch initiates a power off sequence and the rear outlets are then sequenced off. [. . . ] A +5 Volt terminal is also provided to power an external relay or other control circuitry (if required). The following diagrams give just 2 examples of how you would connect. LCD The LCD display on the front panel indicates current AC line voltage and the total load current that the PS8 PRO is supplying. It also indicates time of day (in 24 hour format) as set by the hour and minute switches. The clock draws power from an internal battery whenever power is not available. MAXIMUM LOAD The eight circuit breaker protected outlets are rated at 15 amps total, which is equivalent to 1800 watts at 120 volts. If the total load on the PS8 PRO exceeds 15 amps, the circuit breaker on the front panel will trip, cutting off power to all outlets. If this happens, reduce the overall load by unplugging one or more units from the PS8, then push the circuit breaker button in to reset it. ADVANCED POWER FILTERING The PS8 PRO has specialized internal circuitry to filter out digital and dimmer hash as well as any high frequency noise that is above the audio range. By using both Common Mode and Differential Mode topologies in series for the filter design we are able to block virtually all of the unwanted noise that is between the AC line and ground, and also the two sides of the AC line. This has the additional benefit of reducing ground loop problems in your system. High frequency noise currents in particular are highly attenuated in both directions so that any line noise that could be generated by one of your components is not allowed to get back into your main AC wiring, so if you use a PS8 PRO in your setup, you can distribute and isolate the noisy components from the sensitive components in your system. Additionally, any signals above 10kHz are filtered from the line with typically 40dB of attenuation above 100kHz. The PS8 PRO also protects your delicate electronic equipment with high voltage varistor (MOV) surge and transient suppressors. The fast-acting suppression circuit responds in less than a nanosecond, clamping transient voltages to safe levels. WARNINGS All operating instructions should be read before using this equipment. To prevent the risk of electrical shock, do not remove the cover or the back. There are no user-serviceable parts inside. Please refer servicing to a qualified service technician. Do not expose this unit to rain or moisture or to heat sources such as radiators, stoves, or other items that generate excessive heat. [. . . ] 1) Be sure that the unit is the cause of the problem. Check to make sure the unit has power, all cables are connected correctly, and the cables themselves are in working condition. You may want to consult with your dealer for assistance in troubleshooting or testing your particular configuration. 2) If you believe the ART unit is at fault, go to www. artproaudio. com. [. . . ]
