It offers multiple display options, including a standard 6+1 LCD display, a backlit LCD display (blue backlight), and a mechanical roller display, to meet different reading preferences. The meter supports rated currents of 5(45)A, with operational voltage options of 120V or 220V AC ±10%, and a frequency range of 50\/60Hz. Built to IEC 62053-21 standards with Class 1 accuracy, it offers robust insulation capabilities, low internal power consumption, and long-term data retention of over 20 years during power outages. Some models feature a reset button for convenient data clearing, along with visual indicators including a green LED for power status and a red LED for load consumption and test pulse output. The meter also provides a passive pulse output for external monitoring. Housed in flame-retardant materials with an IP51 protection rating, it is suitable for DIN rail installation in distribution panels. Variants such as DDS238-1, DDS238-1 ZN, and DDS238-1 SW are available to suit specific application requirements.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size:24px;font-family:Arial\"\u003e\u003cstrong\u003eProduct Data
