Panel Meters

A Panel Meter is an instrument use for measuring and displaying electrical or electronic values such as voltage, current, power, frequency, and temperature. Panel meters provide operators with a user-friendly method of monitoring any electrical system, as well as providing feedback so that the system can be adjusted accordingly.

The DCA5-20PC-4-DC1-RL-C Panel Meter is a panel meter designed to measure and display DC current up to 20 amperes. It features a four digital character display, a one percent full-scale accuracy, and a universal power supply, with unipolar voltage input ranging from 1V to 50V. The device is equipped with a relay contact output for alarms. The relay contact output can be used to indicate an alarm status, to regulate current, to activate external events, and/or to logic-disable the device.

The DCA5-20PC-4-DC1-RL-C Panel Meter is most commonly used in applications such as battery charging, fuel cell bi-directional current monitoring, and motor control. For example, it can be used to monitor and regulate the charge state of a battery by activating alarms and/or switching off the charger when the battery is fully charged. Similarly, it can be used in fuel cell applications to accurately measure and display the current flow between the fuel cell and the battery. Finally, the device can be used for motor control, where the analog output enables the current flowing in the motor to be set, monitored, and regulated as necessary.

The working principle of the DCA5-20PC-4-DC1-RL-C Panel Meter is that of an average-sensing current transformer. The device uses a Hall Effect device to measure the magnetic flux created by the current and converts it to an analog voltage which is then amplified and used to drive the digital character display. The device also includes an internal relay coil which, when triggered, switches the relay contact output. This output can be used to activate external alarms or to logic-disable the device.

In conclusion, the DCA5-20PC-4-DC1-RL-C Panel Meter is an ideal solution for monitoring and controlling DC currents in a variety of applications. With its one percent full-scale accuracy and universal power supply, the device is suitable for a variety of applications including battery charging, fuel cell bi-directional current monitoring, and motor control. The device operates by measuring and displaying magnetic flux created by current, and can be used to activate external alarms and/or switch off devices when an alarm state is reached.
