1) Fire-retardant V-0/UV resistant materials used, high temperature resistance, corrosion resistance and security
impact resistance.
2) Clip installation design, simple and convenient
3) Long lifespan design for 25 years
4) Normal working temperature is at -30℃~+80℃
5)
6)
7)
8)
Auto off once the temperature in over 85℃.
The connection cable used is UL and TUV qualified.
24Vdc wiring control way makes it more reliable and stable
More than 200m control distance , which is suitable for C&I solar systems.
Normal installation of PEFS-PL series will be 1/2/4 PV panels VS 1 RSD unit. Typical wiring example below:
Connect the PV panel Positive (+) output connector to the RSD Positive (+) input connector.
Connect the PV panel Negative (-) output connector to the RSD Negative (-) input connector.
3.2 Product Information
4 Installation
Temperature Rise Trigger AC Supply Cut-Off Manual Operation
×
85°
Manual shutdown is initiated within less
than 0.1 second of operation by press-
ing the emergency pushbutton on the
Emergency Rapid Shutdown Switch.
The Emergency Switch can be conve-
niently located at ground level for
easy access or multiple switches can be
installed in different multi-level
building zones.
Automatic shutdown occurs if
the temperature sensor on
board of the RSD detects an
ambient temperature rise
above 85 ℃
Disconnection of the external AC
supply, by whatever means,
causes automatic remote
operation of the Emergency
Rapid Shutdown Switch and solar
panel shutdown.

Notes:
1) The 24VDC power source can be supplied separately with UL certificate and should be class 2 (AC/DC or DC/DC type) with
fast shutdown function (<100ms).
2) Meanwhile, temperature degradation and voltage drop should considered when selecting the DC power source. PEFS-
PL80/120-11 type needs 0.8W minimum, PEFS-PL80/120-21 type needs 1.5W minimum. The control voltage is 21.6V minimum.
3) In-line fuse should be used to protect the 24Vdc cable
4) 24V cable size is 2*0.8mm2 recommended
