Customizations Welcome
Custom input and output voltages and frequencies
50Hz / 60Hz Output Frequency Selectable
Output Frequency Adjustable
10% Output Voltage Adjustable
Single and Three Phase Configurations
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 3,000 feet)

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.

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

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

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

High overload capacity.

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.
