Specifically designed to work as an option for the PTE-100-C, the PTE-FCL has been developed to dramatically expand the application of the PTE-100-C to the most complex relays that require variable voltage and phase shifting capabilities, such as directional, single phase impedance and distance relays.
The PTE-FCL also offers the ability to test frequency relays in the 40 - 70 Hz range.
The PTE-FCL is embedded in the PTE-100-C’s cover lid, which allows its users to upgrade their existing PTE-100-C in a very easy and affordable manner. Due to the limited space available and the relative high power needed by the application, the use of the switching amplifier technology is a must. This allows the amplifier to deliver constant power from 70 V up to 140 V (end of the range), exactly where it is more needed.
The PTE-FCL is extremely easy to use. To reach the desired values a single rotary encoder is used, that has two different modes (Coarse or Fine) selectable just by the touch of a push button.
The multifunctional display and special metering functions already built into the PTE-100-C are used to view the PTE-FCL option s output parameters (Voltage, Phase Angle and Frequency), thus elliminating the need of additional metering elements inside the PTE-FCL itself, with the subsequent cost and space savings.
The input voltage is also taken from the PTE-100-C’s output 4, which delivers 110 V at line frequency and also provides the necessary isolation from the main supply
