The Model 3060-MS is a high power solid state frequency converter
consisting of one to ten 50 kW/62.5 kVA, 3 phase AC Power Sources. The
MS Series oers reliable voltage and frequency conversion and power
monitoring for facilities power and/or AC power test applications. By
adding the external SCU/UPC-32 Universal Programmable Controller, the
MS Series can be operated as a fully featured programmable AC Power
Source complete with arbitrary waveform generation and AC transient
programming.

Maximum System Flexibility and Reliability

Capable of operating as either the master or slave in a multi-cabinet parallel
system. Easy to recongure to meet changing test needs.

Control and Monitor Panel

The 3060-MS is equipped with simple to use front panel controls for set­ting output voltage and frequency. This panel also provides read back
on both AC input and AC output Frequency, Voltage, Current and Power
as well as diagnostic information on system status and operation. For
general frequency conversion facility power applications, the front pan­el controls provide all necessary setting and monitoring capabilities. For
AC power test and development applications, the external SCU/UPC-32
programmable controller may be added as an option.

Rugged, Powerful Output

•

350 Amps of Pulse Current

per phase is delivered by

each 3060-MS for driving non-linear loads. This elimi­nates the need to oversize facility power as is common
for rotary or low quality PWM power systems.

•

Load Power Factor

is not an issue. The 3060-MS will

drive virtually any load without damage or risk.

Excellent Regulation

•

and response time eliminates load
“cross talk.” Voltage sags common to other conversion
methods are eliminated with 150 microsecond re­sponse time to a 50% load step. The output recovers to
± 3% of nominal within less than 1/10th of a cycle at
400 Hz.

Maximum Reliability

•

Each 3060-MS

is capable of operating as either the mas­ter or slave in a multi-cabinet parallel system providing
conguration exibility.

•

Mission Reliability

is ensured. The parallel system ar-

chitecture is such that a failed slave unit automatically
removes itself from the power grid. Should the master
unit fail, the operator can select any other paralleled
unit as the new master from the front panel and restore
system operation.

3060-MS

UMS Option

MS Series Battery Support Systems

With the addition of the UMS Battery Backup option, the 3060-MS can be converted to
an uninterruptable Power Source (UPS). The UMS battery support system for a single
cabinet UMS installation (62.5 kVA, 50 kW) consists of 30 sealed, maintenance free, im­mobilized electrolyte batteries installed in a Zone 4 cabinet. The UMS system DC voltage
regulator provides for automatic charging of the battery system to maintain the proper
oat voltage.

The Leader in AC Power Technology

As a privately held, leading
manufacturer of high-quality AC Power
Conversion Equipment, Pacic Power
Source, Inc. oers standard catalog
products that range in power from 500
VA to >625 kVA. Low-power products
include frequency converters and
Programmable AC Power Sources. High­power systems include programmable
power test equipment, frequency
converters and uninterruptible AC
Power Sources.

Founded in 1971, the Irvine, California,
company was an early pioneer in the
development of linear solid-state power
conversion for use in high-reliability
applications. The company now
manufactures both advanced linear and
broadband switching types of AC Power
Sources.

A battery disconnect is located in the center of the battery cabinet front door.
Battery support time at full load (50 kW) is approximately 15 minutes. The waveform
quality at the end of the battery support time meets the requirements of MIL-STD 1399,
section 300A, Types I, II and III power forms.

On-Line, No-Risk Battery Test

This feature of the UMS system provides the ability to perform a battery test on com­mand from the front panel or RS-232 serial port. Test results are displayed on the front
panel and are available over the serial port as a part of the system diagnostics. A battery
failure during the test will not cause the system to drop the load or distort the output
waveform.

SCU-UPC32 Programmable Controller

12-bit A/D converter. This technique provides exceptional metering accuracy and resolution (20
bits), and delivers a high-delity waveform back to a host computer for analysis. The UPC includes

a remote GPIB interface compatible with IEEE488.2 and SCPI.

© 2012 Pacic Power Source, Inc. Specications subject to change without notice.

The UPC controller is a 3-Phase AC arbitrary waveform
generator and precision AC metering system. Each
waveform stored in the UPC is encoded with 12-bit
amplitude and 10-bit time resolution for each cycle. The
waveform for each phase may be independently selected
and varied in amplitude and phase angle with respect to
phase A. The UPC output metering samples the output
volts and amps at 512 samples per measurement using a
