SEL-734B Full-Size Outdoor Enclosure
The full-size outdoor enclosure allows you to install the SEL-734B Advanced Monitoring and Control System in most pole-mounted locations. Additionally, the enclosure contains extra space to mount accessories, such as radios and gateways. SEL offers a variety of SEL-734B ordering options for capacitor control that come preloaded with acSELerator QuickSet SEL-5030 Software design templates. These templates are customized interfaces that allow you to configure the threshold, time-delay, alarm, warning, and communications settings for capacitor bank control.
Use the preconfigured control strategies, or design your own. SEL’s capacitor bank control templates improve efficiency, increase reliability, and reduce installation time and maintenance costs. User-customized templates allow for greater flexibility, fitting into any smart grid application.
Overview
The SEL-734B delivers leading-edge control to any distribution system. Through accurate measurement, the SEL-734B enables precise control to improve power quality and system efficiency. The following list highlights some benefits and capabilities of the SEL-734B combined with the full-size outdoor enclosure.
- Connect to any type of switch configuration with a variety of control cables.
SEL offers many styles of control cables to fit most applications. If you do not find the cable you need, please contact us. - Alert SCADA operators when the enclosure door is opened.
With the optional door switch, a DNP3 point asserts when the enclosure door is opened. - Withstand harsh environments.
All circuit boards in SEL-734B Enclosures are conformally coated, free of charge. - Prevent vandalism.
Physically secure the SEL-734B with lockable latches and protective cable sleeves.
Choose From Two Full-Size Enclosure Styles
SEL offers the full-size enclosure in two styles: a combined sensor and an individual sensor.
| Enclosure Style | Description |
|---|---|
| Combined Sensor | Contains a single 14-pin circular connector located on the bottom. The connection interfaces with three voltage/current phase sensors and a neutral sensor. All control input/output is made through a 19-pin circular connector. |
| Individual Sensor | Contains three 4-pin circular connectors located on the bottom. Each 4-pin connector connects to a single voltage/current sensor. A fourth 4-pin connector connects to a neutral current sensor. All control input/output is made through a 19-pin circular connector. |
