VSIG POWER ELECTRONICS
The STAMFORD Power Conditioning System (PCS) is a robust power electronics device capable of delivering a clean electrical supply for almost any application:- AC, DC, 3-Phase, single phase, high and low volts, 50Hz, 60Hz, 400Hz . The PCS enclosure is fully sealed to give maximum environmental protection.
Working in conjunction with the STAMFORD Permanent Magnet Alternator (PMA) the packager can produce a full variable speed generating set to deliver high quality output power in a very compact package size giving the benefits of reduced overall size, weight and significant improvements in fuel consumption.
Features:
- Wave form distortion (linear load) – less than 3%
- Wave form distortion (non-linear load, 12 pulse rectifier) - 8%
- Control of engine speed depending upon load
- Fuel savings of up to 25%
- AC and DC outputs at the same time
- Programmable output voltage and frequency
- Multiple inputs from PMA, solar PV, wind, battery etc.

Comparison between STAMFORD PCS and conventional generator offerings:
STAMFORD PCS: |
Conventional: |
Controls engine speed dependant upon the load requirement which allows use of smaller engine |
Engine speed is fixed – the engine and alternator are controlled independently of each other |
Overall gen-set dimensions are reduced – smaller engine, compact PCS unit; utilising full canopy width and height reduces the length of the genset |
Larger engine required plus under utilised canopy space due to alternator size governing gen-set length |
Reduced gen-set weight – Smaller engine, smaller canopy / baseplate, flywheel replacement PMA and PCS |
Larger engine, larger canopy / baseplate, conventional alternator |
Tests have proved up to 25% improvement in fuel consumption by matching the engine speed to the load demand |
High engine exhaust emissions at light loads
Increased engine maintenance at light loads
Poor fuel economy at light loads
Reduced engine life at light loads |
Produces a true sine wave output - Particularly suited to Non-Linear Distorting Loads:
THD Linear Load < 3%
THD Non Linear Load (20% 6 Pulse drive) <5% |
Need to derate for Non-Linear Distorting Loads:
THD Linear Load 3%
THD Non Linear Load (20% 6 Pulse drive) >10% |
Voltage and frequency output can be selected from control panel |
Need to reconnect windings and change settings on AVR |
Unit can deliver AC and DC output at the same time |
AC output only without separate rectifier |
Multiple input possible: PMA, PV Solar, Wind Generator, Batteries, etc. |
