Product Description:
The 265 is a high-current linear amplifier manufactured by Copley Controls as part of the CC High Power Amplifiers series. This module is used in industrial automation to drive large voice-coil actuators, electromagnets, or motor windings with precisely regulated current. By converting low-level command voltages from a motion controller into proportional current, it closes the loop between control software and high-power loads. The compact frame simplifies installation in equipment racks, while an internal heat sink dissipates the heat generated during operation. This arrangement supports applications that require controlled current delivery within a relatively small mounting area.
The amplifier can deliver a continuous output of ±150 A, enabling it to operate high-force actuators without external boosters. For transient events such as rapid acceleration or impact damping, it supports a peak output of ±312 A. The small-signal bandwidth extends from DC to 4 kHz, so commanded force profiles with frequency content inside that range can be reproduced without significant amplitude loss. A slew rate of 9 V/µs limits how quickly the output voltage can change, and this value works with the load inductance to determine the maximum current rise time. Internally, the output stage switches at 80 kHz, placing ripple components well above the control bandwidth and reducing external filtering requirements. These electrical characteristics allow the amplifier to respond quickly while maintaining controlled current through demanding inductive loads.
The power bridge uses MOSFET devices, providing low conduction losses and fast switching that complement the stated slew rate. Total harmonic distortion is limited to 0.2%, which keeps the current delivered to precision electromagnetic loads close to the requested waveform. Long-term drift is reduced by a DC offset stability of 5 mA/°C, helping force or field strength remain predictable as the ambient temperature changes. Up to 20 units can be wired in parallel to increase current capacity for exceptionally large coils while maintaining consistent dynamic behavior across channels. Parallel operation also allows the required output capacity to be distributed among multiple amplifier modules. Proper current sharing and thermal management are necessary when several units operate together under sustained high-current conditions.
