The EPC9513 is designed to operate in conjunction with EPC9127 (10 W EPC9510), EPC9128 (16 W EPC9509), EPC9120 (33 W EPC9512) and EPC9121 (10 W EPC9511) transmitter units. The EPC9515 is designed to operate in conjunction with EPC9128 (16 W EPC9509), and EPC9120 (33 W EPC9512) transmitter units.
These loads have low control bandwidth a. Operation using the pre-regulator and will cause the EPC9128 system to oscillate at a low frequency and may lead to failure. It is recommended to use a fixed low inductance resistor as an initial load.
