Advanced-Data Logging

A12B 52-Series is equipped with a time & event-based data-log with a battery backup for a real-time-clock stamp, written to\ a removable micro-SD card. This allows trending the health of your DC system and provides knowledge of the history leading up to the event.

1. Optional DC Breaker when ordered in lieu of standard fuse(s) may slightly differ in ratings. AC Draws shown with asterisk* when equipped with AC Breaker, a series fuse is included.
2. AC Current Draws based @ 100% load and standard battery cells of 6L (12V), 12L (24V), 24L (48V) and 60L (130V). Maximum Current Draw is 120% of ratings shown. AC Current draws shown in Italics have high current draws for their specific input voltages – verification of input power requirement should be done prior to ordering.
3. Denotes units not U.L Listed
4. Case sizes shown are for standard 60 Hz units and may differ depending on optional accessories and/or 50Hz input. Please consult factory when dimensions are critical.
5. Denotes units not UL 1481 Listed.
