Suitable for many electrical and electronic systems for on-board transportation, communication and industrial applications, Premium’s dc ac inverters cover a power range from 260 to 4500VA and are available with dc inputs covering 12/24/36/48/72 & 110V dc.
The research and design facility at Premium’s headquarters in Spain implements extensive controls from design concept through prototyping and production, in an effort to ensure “high” quality and performance in product development and service life.
All products go through accelerated life testing under full load and extended temperature conditions, which helps to identify any component weakness from an early stage. Test facilities include:
Climatic Testing- Performed in an environmental test chamber from -40ºC to +100ºC. Measurements are made and recorded on key components, both at static temperatures and also with sharp ramps in the thermal profile.
EMC Testing- Conducted in house from an early point in the design phase. Emission and Immunity tests are performed in a test chamber including the ability to perform electromagnetic field tests up to 20V/m and 1GHz.
Electrical and Fire Safety– All products have been designed in accordance with EN60950, with a planned migration to EN62368. Products are also tested EN45545-2 for fire safety and, more generally, to the requirements of EN50155 for the railway industry. This is an integral part of the design phase with regular design reviews to ensure compliance at all stages.
Premium’s most recent additions include the ODS (single phase output) and ODX series (three phase output) inverters which have been designed for motor control applications. These include the following features:
- RS-232 port: Used to configure and control the unit
- Phase inversion: Used to define the motor rotation direction
- Programmable output voltage and frequency
- Programmable soft start (control of voltage and frequency)
- Choice of different input voltages
- Isolated alarms
