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.

System Features:

• Voltage and Frequency Conversion.

• Highly Flexible and Expandable Power

Architecture with Unique Master/Slave

Configuration up to 625 kVA.

• Very High Current Capability.

• Low Voltage Distortion.

Included with Standard Delivery:

• 3060-MS Solid State Frequency Converter.

Optional SCU/UPC32 M993235 Remote Controller

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.

Solid State Technology

3060-MS

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.

Low Installation Cost

standard doorways. Audible noise is limited to cool­ing fans. There is no 400 Hz whine that requires
noise isolation. Solid state design with a forklift base
eliminates the need for concrete pads and vibration
isolators common to rotary installations. Casters are
optional if desired.
