Current circuit Each phase: 0.1 VA
Auxiliary power circuit 13 VA (at 110 V AC), 14 VA (at 220 V AC), 9 W (at 100 V DC)
Auxiliary power 100 V to 240 V AC (±15%), 100 V to 240 V DC (-30% +15%)
Weight 0.5 kg
Dimensions 96 (H) × 96 (W) × 90 (D) mm
Mounting method Embedded
Operating temperature/humidity -5°C to +55°C (Daily average temperature: 35°C or less), 0% to 85% RH, Non condensing
Storage temperature/ humidity -25°C to +75°C (Daily average temperature: 35°C or less), 0% to 85% RH, Non condensing
Note 1. The class value represents the ratio to the rated value (100%).
Note 2. For measurement where the harmonic distortion ratio (content rate) is 100% or more, the class can exceed ±1.0%.
Note 3. Harmonic current cannot be measured without voltage input.
Note 4. Using the conventional ME-4210-SS96 (Optional Plug-in Module), the CE marking and UL standards safety certification requirements cannot be met.
*1: Integrated values (Wh, varh, and VAh) are measured values of ME96SS. They are not differential values by logging period.
