Product Description:
The EEA-PAM-525-C-30 power amplifier card is manufactured by Vickers and belongs to the EEA-PAM Power Amplifiers series. It mounts inside control enclosures where it converts logic-level commands into stable supply and reference rails for industrial motion or hydraulic equipment. By housing the conditioning circuitry on a dedicated board, the module simplifies wiring between the machine controller and the field devices, while its solid-state design supports the fast response times expected in automated production cells.
Normal operation requires a system voltage of 24 VDC; under this input the module draws about 40 W. Internal DC-DC converters create a dual control rail of ±15 VDC that can supply up to 50 mA for external sensors or command electronics, and the ripple on that rail is limited to 50 mV peak-to-peak. The board tolerates line distortion up to 10 % pk-pk thanks to on-board filtering. Reverse polarity protection prevents damage from swapped leads, and the outputs are short-circuit protected so a downstream fault will not harm the card. Reference voltage tolerance is kept within ±1 % to support precise closed-loop control.
Command functions use a stabilized reference of ±10 VDC at up to 5 mA, with ripple held to 20 mV peak-to-peak. Logic enabling circuitry presents an input impedance of 22 kΩ; the amplifier switches on when the line rises above 9.8 VDC and drops out below 4.5 VDC. Protection features include automatic shutdown at 18 VDC to guard against brownouts. Together with the affirmative short-circuit and reverse-polarity safeguards, these thresholds ensure the board delivers consistent performance even when input quality varies. These design limits let the amplifier drive proportional valves or other inductive loads without loss of accuracy.
