V2 Technologies SE350 Automatic Voltage Regulator 2 in 1 accessory

SKU CH-DR5Z-P87ZH

Regulates generator output voltage with 1.0% accuracy, sensing 190–240 Vac and delivering up to 525 W forcing power

  • Precise 1.0% voltage regulation keeps generator output stable
  • Wide 190–240 Vac sensing input handles fluctuating mains supply
  • Continuous 255 W exciter power sustains load without overheating
  • Adjustable 45–64 Hz roll-off matches 50 Hz and 60 Hz systems
  • Built-in EMI filter and 10 Vac residual start-up simplify installation

Generator voltage regulation

The V2 Technologies SE350 is an encapsulated automatic voltage regulator designed as a generic replacement for brushless AC generators. It controls exciter field current to maintain stable output across 190 to 240 Vac sensing and power input. The unit suits technicians maintaining gensets that require 1.0% regulation accuracy and automatic voltage build-up from residual voltage as low as 10 Vac.

Input and output boundaries

Sensing and power input accepts 190 to 240 Vac with a 500 VA burden. Continuous output delivers 73 Vdc at 3.5 Adc for 255 watts, while forcing output at 240 Vac input reaches 105 Vdc at 5 Adc for 525 watts. Frequency compensation rolls off between 54 and 64 Hz for 60 Hz systems and between 45 and 51 Hz for 50 Hz systems. Power dissipation peaks at 8 watts.

Installation and common issues

Remote voltage adjustment uses a 2000 ohm rheostat for 10% range or a 1000 ohm rheostat for 5% range. The module operates from -40C to +60C and stores down to -60C. Installers must match rheostat value to the desired adjustment span and verify generator residual voltage exceeds the 10 Vac build-up threshold. Internal EMI suppression reduces interference but does not replace external filtering where regulations demand it.

Questions about this item

Which SE350 AVR version should I choose for my generator?

The SE350 is a single-model automatic voltage regulator with sensing and power input rated 190 – 240 Vac and a 500 VA burden; select it when those ratings match your generator’s specifications.

What does the 1.0 % regulation figure mean once the unit is installed?

It means the regulator holds the generator’s output voltage within ±1.0 % of the set point from no-load to full-load conditions.

What interface standard does the SE350 use and what does it cap in practice?

The module connects via hard-wired generator leads; its continuous output is capped at 73 Vdc, 3.5 Adc (255 W) and forcing output at 105 Vdc, 5 Adc (525 W).
