► 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 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).
► 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
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 will 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

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. | |

| MTBF | > 175,000Hrs | Belted: 20,000 ~ 32,000Hrs Single shaft: 30,000 ~ 60,000Hrs | |
| Maintenance | No moving parts to wear out or break, Iess 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 Iagging power factor that increases with load. | |
| Active type | IGBT / PWM | Motor-Generator | |

| 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 overloadcurrents 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. | |
