GENERAL PRODUCT DESCRIPTION

The intended use of the Pacific Power Source MS-Series equipment is basic
frequency or voltage conversion with manually adjustable settings.
optional external programmable controller (UPC) it is suitable for testing
applications such as sag, surge, etc. The MS-Series power sources are a family
of Line-Conditioners/Frequency-Changers covering the power range from 62.5 to
750 kVA (50 - 600 kW), at output frequencies of 50 - 400 Hz. The basic 62.5 kVA
/ 50 kW unit is designated as the model 3060-MS. Up to 12 units can be
paralleled to provide 750 kVA / 600 kW.

MANUFACTURER, THE PROTECTION PROVIDED BY THE EQUIPMENT MAY BE
The 3060-MS functions as a double conversion power source. Input AC power is
rectified to DC by a special power supply that provides both isolation and low
input current distortion. The DC power is then converted back to AC by a high
frequency pulse-width modulated inverter stage, under the control of a highly
stable digital oscillator.
The 3060-MS unit is designed to provide high quality output power.
regulation and total harmonic distortion are of the order of 1% at 50 or 60Hz and
2% at 400Hz. Response time to a 100% step load change is 300 microseconds.
The machine is therefore capable of delivering very high pulse current loads.
The fast response time and excellent regulation of the MS-Series are extremely
important in applications where mixed or switched loads may cause power
interference and load "Cross-talk".
MS Series equipment is designed for long term, continuous operation in a
sheltered (no rain) environment. Because there are no batteries, it will accept a
wide ambient temperature range.
circulates little cooling air and is relatively tolerant of dusty environments.
The MTBF of a single cabinet 3060-MS is high (approx. 5 years).
System operation is controlled by simple, high reliability digital logic.
microprocessor provides internal diagnostics and communicates with the
operator via a 160 character digital display.
