1.1 AcuDC 210/220 Overview
Powerful Multifunction Power Meter
AcuDC 210/220 Series multifunction intelligent power meter can measure DC
voltage and current with high accuracy. Analog output can be used in DCS systems
or industry control systems. Large character LCD display with backlight provides
clear real-time monitoring data readout. This DC meter is designed to meet the
requirement for DC power measurement and monitoring.
Compact Size and Easy Installation
With the size of DIN96 ×48 and 71mm depth after mounting, the AcuDC 210/220
meter can be installed in small gear. Fixing clips are used for easy installation and
removal.
Ease of Use
AcuDC 210/220 utilizes a large character LCD display for clear electrical parameter
readouts. All setting parameters are accessible by using front panel keys or

communication port (if equipped). Setting parameters are protected in EEPROM,
which will maintain its content after the meter is powered o. With the backlight
of the LCD, the display can be easily read in a dim environment. The backlight "ON"
time duration is programmable.
High safety, high reliability
AcuDC 210/220 meter was designed according to industry standards. The meter
receives IEC emission and immunity compliances and is able to operate reliably
under high power disturbance conditions.
