crystal oscillator controlled frequency, free from any spikes, surges, lightning and

frequency fluctuation.

By use of advanced technology  DPS, IGBT and Switching Components to increase the

reliability, efficiency and heat dissipation

COMPLETE INPUT TO OUTPUT TRUE GALVANIC ISOLATION DESIGN
 

Solve ultimately power problems, including noise, lightning, ground leakage current,

and CEMF (Counter-electromotive Force) etc.

 

RELIABLE INPUT PROTECTION
 

Circuit breakers are placed in each individual input loop to ensure power can continuous

through another loop in case of breaker trip caused by an abnormal condition.

INPUT SURGE PROTECTION
 

MOV (Surge Protectors) are added at the input, providing sufficient protection to both

the unit and the load from any ligntning or surge caused by neighboring large loads.

EMI SUPPRESSION
 

An EMI Filter is fitted to meet the international EMI limits.  Therefore, very low noise is

emitted, to prevent interference to other equipment connected to the same AC source.

RUGGEDNESS
 

The rectifiers employ phase control technology to regulate the DC bus voltage.  SCRs

are employed as rectifiers to take advantage of their ruggedness under poor conditions. 

In addition, inductors are used at the input to avoid deforming the AC source waveform.

±20% WIDE INPUT VOLTAGE RANGE
 

The SPM series is designed to accept a wide input range, it can work effectively under

any unstable AC source. All of the input components used are specially selected to

handle extremely high voltage and high current.

MULTI-CPU DESIGN AND SOFTWARE / HARDWARE COOPERATE CONTROL
 

Several CPUs are employed in the control circuit, critical functions are designed to

parallel redundancy to improve reliability.

DIAGNOSTIC PANEL WITH LCD AND LED DISPLAY
 

•  LCD display Real time status, data or historical

   events and parameter settings.

• 24 Status LEDs represent all of the up to date   

   information for clear and in time troubleshooting.

MODULAR DESIGN PCB WITH COLOR MANAGEMENT INDICATORS
  All PCBs are Modular design and integrate

inside the PCB Holder.  In case the SPM series

were failed, open the holder, visual inspect the

indicator color with beneath descriptions for

easily find faults and replace  the PCBs at once.

PLUG & PLAY MODULAR DESIGN FOR QUICK MAINTENANCE AND TROUBLESHOOTING

 

The power circuit is separated into several modules plugged into several slots in the unit,

which are easy to pull out, permitting quick maintenance and easier troubleshooting

(MTTR < 25minutes).

 
TOLERATE HARSH ENVIRONMENT
 

Each component is chosen with large safety margin to accommodate Extreme

environments, such as temperature, humidity, altitude, shock or Contamination.

EACH PHASE WITH INDIVIDUAL INVERTER SUPPORTING
 

Characteristics will not be violated under 100% unbalance load.

►  BASE WITH ANCHOR BOLT FIXING
 

The floor loading capacity should be high enough

to endure the weight of the SPM series.

The SPM series is mounted on four right-angled

steel angles.   Insert corresponding bolts and nuts

2  (dia. 1/2")  into the floor for securing the SPM

series on the floor when it is located in an area

where earthquakes is possible, or where motion

may occur, e.g. vehicle  mounted.

 

 

INTELLIGENT FAN ROTATION RATE CONTROL
 

The fan rotation rate  can automatically change according to the load condition, so that

 the fan’s life expectancy is extended and audible noise is reduced.

REASONABLE HEAT EVACUATION PASSAGE DESIGN
 

Control circuitry and power circuitry are physically separated. Thus, the SPM series

can operate under harsh environment.

BATTERY can be added for UPS Capability
 

The SPM series can be started without an AC source, that is, can be started with battery

power only. This is possible because current limit circuitry is added, preventing the problem

of large inrush current from blowing the battery fuse and damaging the DC capacitors when

batteries are connected to an empty DC bus (before the DC bus is energized).

INPUT HARMONIC FILTER
SERIAL & PARALLEL REDUNDANT CONNECTION
 

A supplemental power supply is added to provide redundancy for supplying power to the

static switch, so that there will be AC output no matter what happens to the Frequency Converter.

Reduce harmonic current for 80KVA and above SPM series.

EMERGENCY STOP SWITCH
 

Be installed outside or nearby the Frequency Converters for stopping the Frequency

Converters output in case of emergency.

SHOCK MOUNT
 

The cabinet can be shock mounted using optional rubber or coil type isolators. This will

enable the unit to withstand shock levels as specified in MIL-S-901.

For portability, the cabinets may be optionally equipped with the base-mounted caster / leveler

set as shown.

CABLE ENTRANCE DIRECTION
 

Cable entry can be from Front, Side, Rear or Top side

INTRODUCTION
 
Static Frequency Converter :

The static frequency converter used semiconductors to rectify AC source power at source frequency

and voltage into DC power before using an inverter to generate a new AC power at the required

frequency and voltage from the DC power. There are no moving parts except for some cooling fans

in the converter.

 
Key features are :
1. The input and output are isolated via isolation transformer
2. The output voltage regulation can be stable up to 0.2%
3. The output frequency can be very stable up to 0.01Hz
4. The output voltage and frequency can be variable to suit testing purposes
5. Suitable for indoor application with air-conditioned ambience
6. Compact in size which save space for installation
   

 

WHY DO YOU HAVE TO CHOOSE STATIC FREQUENCY CONVERTER INSTEAD OF ROTARY FREQUENCY CONVERTER?

 
1) RELIABILITY :


Unlike rotary generator sets, Static frequency converters have no moving parts to

wear out or break. The result is higher dependability, longer MTBF, and shorter MTTR.

2) MAINTENANCE COSTS :


Those moving parts in the rotary generator sets have to be serviced and maintained on

a regular basis, or the risk of premature failure increases even further. Static converters

require no such maintenance, dramatically reducing the cost of the converter over its

useful life.

3) NOISE :


Since Static converters have no moving mechanical parts generating a loud racket,

the only sounds heard from the unit come from the small cooling fans and the transformer.

The result is very quiet operation ? Typically 55 dBA at 1meter distance.

4) SIZE:


Typically, Static converters of any given power output ratings are much smaller and lighter

than rotary generator sets of the same power output rating.
