Product Description:

Power amplifiers are necessary automation devices that can magnify small signals and process them based on some logic or condition. In a typical industrial system, power amplifiers are heavily utilized for applications involving servo machines and modules such as motors and drives. Vickers is one of the most trusted names that specializes in the production of intelligent power amplifiers. Specifically, Vickers offers impressive power amplifiers with a command logic module and two ramps under the EEA-PAM series. The EEA-PAM-561-B-32 is an original Vickers module that supports four inputs with quadrant detection during operation.

Like other power amplifiers engineered by Vickers, the EEA-PAM-561-B-32 employs a set of status LEDs and adjustable potentiometers. Each potentiometer in the EEA-PAM-561-B-32’s front panel can be used to control the ramp times of the amplifier. To adjust the potentiometer, external voltage signals must be used. Aside from the built-in ramp potentiometers, this module also offers a dedicated potentiometer for each of the input signals. To operate properly, this power amplifier must be connected to a DC supply with a terminal potential difference of 24 V. During operation, the unit can tolerate a minimum voltage of 20 V and a maximum voltage of 40 V.

Since DC power amplifiers such as the EEA-PAM-561-B-32 are generally expected to operate only at the positive voltage region, this product employs reverse-polarity protection. Whenever the voltage of the amplifier goes below 18 VDC, the product automatically shuts down. Another advantage of this power amplifier over other competitors on the market is that all the outputs of this device are short-circuit protected. During nominal operation, this amplifier by Vickers can tolerate a maximum solenoid current of 1.8 A.
