LPI® Photovoltaic Shunt Protector - PV140

Product Description The LPI PV140 is a surge protection device rated for 40kA 8/20μs single shot surge capacity (Imax). The unit is designed for protection of positive and negative busbars of photovoltaic systems against the surge effects according to EN 61643-11 and IEC 61643-1. It is also designed for easy mounting on standard 35mm DIN rail. The unit comes with fast, responsive Metal Oxide Varistors (MOV) to provide effective surge protection with low let-through voltage to protect sensitive electronics and electrical circuits. The PV140 is fitted with thermal disconnects which will respond should the varistors be overloaded. In this case, the indicator changes status to red, and alarm contacts change over. The unit comes as a two part item. The base is hardwired into the circuit to be protected, and the protection module is plugged into this

base. This enables easy replacement of protection modules should they be degraded or damaged by excessive transient activity.

A set of voltage-free contacts integral to each of the PV140 protection mod-ules provides the facility to monitor the protection status. With the protec-tion module fully operational, the status indicator will be green and terminals 1 & 2 on the remote monitoring terminals will be connected. When the PV140 protection module MOV material degrades to a point where replace-ment is necessary, the status indicator will change to red and the voltage free contacts will change state so that terminals 2 & 3 are connected (see Figure 2)

Installation:

Remote Status Indication

1. Fix the PV140 modules onto the DIN rail.

2. Connect the positive terminal to one side and the negative to the other side.

3. Series connect the normally closed alarm contacts (1 and 2) for remote monitoring.

4. The PV140 is a pluggable module and the pluggable unit can be replaced (when the indicator turns red`) without disconnecting the power supply.

5. Modules marked with an asterisk in Figure 1. are only necessary if neither the +ve or the –ve wires are locally grounded.
