OJ Electronics launches new single-phase 1.3 kW ventilation drive
OJ Electronics has expanded its OJ DV range with a single-phase ventilation drive that can be placed outside the airflow in ventilation systems – and maintain 1,300 W shaft power even at +40˚C. The new 1.3 kW drive is ideal for installations where phase load sharing is handled manually, and for refurbishment projects where only single-phase supply is available.
OJ Drives now available in single-phase power size 1.3 kW The OJ DV product range of drives dedicated to ventilation systems has been extended with a thirteenth variant in the single-phase supply range. The new OJ DV-1013 has a larger housing than the existing H1 variant. This enables placement outside the airflow, thereby making installation very flexible. The unit is self-cooling: its large cooling ribs ensure sufficient cooling without the need of airflow through the ribs, which means that you get 1,300 W shaft power up to ambient temperatures of +40˚C.
Ideal for manual phase load sharing and low supply ranges Manual handling of phase load sharing is widely used in livestock house applications. It allows for flexible supply distribution, ensuring continuous ventilation even in cases where a grid/supply phase is lost. This ability is highly useful when designing new livestock farms. So too is the wide supply voltage range, especially in the low end of the spectrum. The OJ DV single-phase products can deliver full power down to a supply voltage of 190V and will continue to spin the motor down to a supply voltage of 160V.
Single-phase supply: excellent for refurbishment of older buildings Older buildings in particular are not always equipped with a three-phase supply installation, and in refurbishment cases it can be difficult to change the supply installation. Therefore a single-phase drive with higher shaft power will be an attractive offering for many clients.
The new OJ DV variant has all the benefits of the OJ DV range: • Flexible design • Operation from -40 to +50 degrees • Energy efficient • Integrated EMC filter • User-friendly connection
Features of the OJ DV series: With 13 power variants (from 0.5 to 15 kW), different module options and options for mounting inside or outside the airflow, OJ DV drives can be customized to fit any fan solution. The drives are quick to install, simple to customize, easy to mount and will work in any conditions.
Fully integrated EMC filter The OJ DV series comes with a fully integrated EMC filter. The complete product range meets norms for emissions and immunity in industrial and residential areas EN 61800-3 (C1 and C2 class).
