July 18, 2013 – Micropac Industries introduces the IPC01 series of Industrial Power Controllers. The IPC01 devices are available in 400VDC / 5A, 75VDC / 10A, 280VAC / 5A, and 40VAC / 10A versions, each allowing remote switching, load protection and output status monitoring. Upon detecting an overload condition, the IPC01 immediately shuts off the load and provides a status for monitor by the system controller. The system controller may then take the appropriate action such as resetting the IPC01 (control signal reset, no need to cycle power), implementing contingency or backup systems, or logging for maintenance. If reset, the IPC01 will continue to monitor for overload conditions and provide load protection.
A typical application could include a single and appropriate upstream branch protection device, multiple loads switched and protected by individual IPC01 devices, and a system controller. When main power is applied, the IPC01 devices power up in the “Off” state and report “Off” to the system controller. The system controller can then turn on one or more IPC01 controlled loads. As the IPC01 turns on it will report “On” to the system controller providing positive feedback. If an overload is detected the IPC01 will turn off the load and report “Off” to the system controller providing a direct indication of the overload.
Only the affected load is shutdown, all other IPC01 and respective loads remain operational. The system controller can command the “tripped” IPC01 “Off” and then “On” to reset and turn on the IPC01. System designers may utilize that status to implement backup / contingency operations, load shedding, maintenance logging, or another appropriate action based on the reported fault. The IPC01 is designed for harsh industrial applications and is fully temperature rated for operation from -40°C to +80°C with no heatsink, simplifying system thermal design considerations. These devices can be mounted in enclosures with limited ventilation or directly to hot equipment.
