400Hz Input and / or Output Frequency
BATTERY added for UPS Backup
 

The SPF 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).

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.

12-PULSE FULL CONTROLLED RECTIFIER
 

Reduce harmonic current for 80KVA and above SPM series.

Emergency Stop Switch (EPO)
 

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

Converters output in case of emergency. 

SHOCK MOUNT OPTION
 

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

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

CASTERS & LEVELERS
 

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

       



COMMUNICATIONS OPTIONS  
   
UPSCANTM - Remote Control Panel

 

 

A hand held remote display and control module

with LCD and LED display that can monitor up

to 99 Frequency Converters via RS-485 at a

remote distance up to <1,000M (up to 3,000feet)

GPRS MODEM  - Auto-dialing Module   

 

 

In case of abnormal situation, it will automatically

dial to specified service center for help. Multiple

phone numbers can be set and no dedicated line

is required.

UPSCOMTM - 3 Phase PC Monitoring Software  

 

 

 

Can provide real-time three phases information

of  Frequency Converter connected on the line

and monitor 31 Frequency Converters max. with

one PC.

3 Phase SNMP Card   

 

 

 

Can monitor and manage the Frequency Converters

through Web browser and Java applet, providing

simultaneously three phases data acquisition.

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 BUY FREQUENCY CONVERTER?
 
 1. Install Frequency Converter ahead of loading equipment. No need to re-modify.
 2. Save money. Change of frequency will cause some internal alterations different to original design,
  the manufacturer would refuse to provide free warranty and repair.
 3. In addition to Frequency Conversion, it can work as a Voltage regulator with more accurate and
  consistent voltage regulation rate.
 4. Auto shutdown for overload, over / under voltage, over current, over temperature and short circuit
  protection
 5. Economical price if compare to AC Power Source / VARIABLE Frequency Converter. 
   

 

COMPARATIVE LIST

between Static Frequency Converter and Rotary Frequency Converter

 
 

SOLID STATE TYPE

(STATIC) TYPE

MOTOR TYPE

(ROTARY) TYPE

 Active type IGBT/PWM Motor-Generator
 Technology

Convert incoming AC power into DC,

and then convert the DC into the

required output power.

Use input power to run a motor,

which produces mechanical

energy to spin a generator,

which in turn produced the

required output power.

 Capacity 500VA ~ 1000KVA 500VA ~ 500KVA
 Size Compact size

Bigger Size;

Rugged floor mount

construction

 Weight Lighter Heaviest

 Environmental

 Objections

Fewer,

e.g., generally Quieter, Lighter weight,

etc.

Some,

e.g., Audible Noise, Heavy

Weight, Waste Space Factor, etc.

 Output
  Frequency

Generally fixed

(50, 60 or 400 Hz Output Frequency

can be fixed or variable.)   

Generally fixed
 Output Transformer Yes Option
 MTBF    > 175,000Hrs

Belted: 20,000 ~ 32,000Hrs

Single shaft: 30,000 ~ 60,000Hrs

 Maintenance

No moving parts to wear out or break,

less or no preventive maintenance

other than cleaning fans,  exhausts   

Preventive maintenance is

required, e.g., bearing

maintenance, belt replacement

(except single shaft units),

cleaning air intakes and

exhausts

 Preparative Work

Some installation and setup may be

required, but usually less than rotary

alternative

 Some installation and setup is

required, e.g., concrete pad,

power circuits

 Crest Factor

Input current has high crest factor

that also caused leading power factor

that increases with load.

 Input to the converter motor has

lagging power factor that

increases with load.

 Active type IGBT / PWM  Motor-Generator
 Response Time 60ms ~ 2ms Slow
 Distortion  Input

Harmonic distortion and noise on

the input. Power is not normally

passed to the output 

Harmonic distortion and noise

on the input. Power is not

passed to the output

 Output

Output harmonic distortion is

moderately lower, ≦2%   

Output harmonic distortion is

low, < 4% ~ 5%.

 Waveform PURE Sine Wave Output  PURE Sine Wave Output
 Impedance Very low output source Impedance  Low output source impedance
 Overload Capacity

High overload capacity.

Typically can withstand 300% of

transient peak current than rated

capacity.

Can source heavy overload

currents 2 ~ 4X for short periods

of time, depends upon generator

windings and momentum of

rotating components. Overloads

generally cause voltage

reduction but not large waveform

distortion.

 Full Load Efficiency  Approx. 85% ~ 94%

< 6.25KVA units: 60 ~ 65%;

large units: 85% ~ 92%

 Suitability

Varies with load, better with heavy

resistive loads and lower output

frequencies.

 Varies with load,

better with heavy loads.
