PTE-FCN relay testing voltage source

PTE-FCN relay testing voltage source

Variable Voltage, Frequency and Phase Angle Source

The PTE-FCN is an independent adjustable voltage source that can be installed inside the PTE-100-C’s lid in a few minutes.


It is the easiest and most economical way of increasing the relay types that can be tested with the PTE-100-C. The PTE-FCN includes its own LCD display and a BUS-PTE connection, which makes it easier to operate and enables it for use in combination with any other test set in the PTE range. The PTE-FCN is included as standard in models PTE-100-C Pro and PTE-50-CE Pro.
