• Current—Ia, Ib, Ic, In, I avg.
• Current unbalance rate –I unbal.
• Active power –Pa, Pb, Pc, ΣP
• Reactive power –Qa, Qb, Qc, ΣQ
• Apparent power—Sa, Sb,Sc, ΣS
• Power factor—PFa, PFb, PFc, ΣPF
• Frequency--F
• Active energy—Total kWh (import / export )
• Reactive energy–Total kvarh(import / export )
• Apparent energy –Total kVAh
• Demand (I, P) and Max. demand record for I, P
• 31stharmonic, THD, THDu, THDi,
• SetpointAlarm –over voltage, under voltage, over current, under current, frequency too high, frequency too low, over load, over demand, phase loss, status input off

Optional Funtion

• 2 Status inputs (Wet Contact)
• 2 Relay Outputs

For example :

SPM32-RS-V1, it meansthedevice provides basic measuring function, one RS485 port, 2 digital inputs, 2 relay outputs. Rated input current 5A.
