Junction Box

Introduction

Features

1. On/off switch is operated by wireless remote control and an internal data sensor works as civil twilight time in the no service area of remote control.
2. Unstable voltage would result in a reduction of a safety device/lamp life due to a simultaneous lighting at the beginning in the dark. To stop such problem, half lighting system(Every other light is on) is available.
3. Extra timer is attached in wireless control equipment in case of defect.
4. Two circuits are available for all night light and every other light. Every other light can be applied separately when necessary.
5. Hand on/off mode is possible when inspecting any status and necessary.

Structure

1. Body is an airtight box to avoid dust, smoke, and corrosion.
2. Air filter is attached to the both side of the control box so as to be easy-cleaned and replacement and an extractor fan is installed to the left side for an air circulation in the box.
3. Enhanced electric master key using for easy security and management.
4. Checking a electric meter in the box through the sight glass.
5. Self-stand, Open-fronted, Semi-cubic airtight, and power/load/control/meter as 4 parts.
