UNiKA PD-5 Power Sequencer
OVERVIEW
INTRODUCTION
The PD-5 provides controlled power sequencing to 8 rear AC outlets. This allows you to control the power-up and down sequence in a system to minimize turn-on transients and the damage that they may cause. Sequencing power on also smooths out inrush currents. The PD-5 is also a full-featured power conditioner with Advanced Power Filtering, a fast-acting breaker, as well as surge and spike protection to protect your system. Additionally, a front panel LCD display gives you a constant read of AC line voltage and load current as well as a built-in system clock. The PD-5 is designed to sequence and protect a wide range of equipment from sensitive tube preamps to powered speakers, large displays, or digital systems. Your equipment will sound and work better and live longer.

OPERATION
POWER SWITCH
The PD-5 has a master POWER switch for the rear outlets. This switch glows
when the unit is enabled, 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.
LCD
The LCD display on the front panel indicates current AC line voltage and the
total load current that the PD-5 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 110 volts. If the total load on the PD-5
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 PD-5, then push the circuit breaker button in to
reset it.
ADVANCED POWER FILTERING
The PD-5 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 PD-5 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 PD-5 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.
- This unit should be cleaned only with a damp cloth. Do not get moisture inside the unit.
- When moving this equipment, it should be placed in its original carton and packing, to reduce the risk of damage in transit.
