Product Description:
The EEA-PAM-525-A-30 power amplifier is a robust and efficient device designed for industrial automation applications requiring precise power control. This power amplifier supports a nominal power supply of 24 V DC at 50 W. It offers advanced protection features and ensures reliable performance across various operational conditions.
This Vickers EEA-PAM-5**-A-30 power amplifiers series module supports an input voltage range of 20 V to 40 V DC including peak to peak ripple tolerances of ± 10 %. If the voltage drops below 18 V DC, this amplifier shuts down to prevent system malfunction. Reverse-polarity protection safeguards this model against incorrect power connections. The amplifier’s signal source capabilities include ± 15 V at 50 mA maximum for z22 and b22 connections with a peak to peak ripple of 50 mV. For z2 and b2, it supports ± 10 V (± 1 %) at 5 mA maximum with a ripple of 20 mV. This module is engineered to maintain a low temperature drift of less than 1 mV/°C (± 0.5 mV/°F) and operates within a temperature range of 32 °F to 122 °F. The output circuits are short circuit protected that enhances the device's resilience against potential electrical faults.
The EEA-PAM-525-A-30 power amplifier also features pulse width modulation (PWM) with built in short circuit protection to prevent damage during operational anomalies. The dither function which is factory-set ensures optimal performance without requiring manual adjustments. This amplifier's ramp time adjustment is preset at the factory but it can be configured within an adjustable range of 50 ms to 5 seconds for both ramp up and ramp down processes with a minimum ramp time of approximately 50 ms. This adjustability provides flexibility for applications requiring customized ramp rates.
