TRANSCRIPT
Dual Source Energy Meter: EM6438 & EM6436 Dual
Two Energy Registers (Utility-U & Generator-G) separately record consumption based on a Control Signal for Dual Source energy billing.
Digital meter with analog indicator Compact Smart
Dual Source Energy Meter: EM6438 & EM6436 Dual
Features & Benefits
G.Sense Indicator glows when the generator source is detected by G Smart Sensor
Auto Scaling kWh, MWhUnique 8 segment 3 line LED display Tenant can pay accurate energy bill as per G usage instead of monthly maintenance,
%A Full scale Load bar n Color coded Analog indication n Track generator overloading, eg Shopping malls
Smart Keys. One Touch U & G Energy. nSimple - auto scrollingTrue RMS, Accurate on distorted and unbalanced loads G Smart Sensor
n18 to 60 Vdc / 80 to 300 Vac Universal (Noise filter. Eg. spikes, neutral to earth voltage)
nSupports Multiple generator paralleling & bus coupler islanding schemes
nIn case of load sharing entire consumption is directed to ‘G’ register. For separate monitoring of each source consumption, EM 6436 for each source with common EBS software is recommended
nOptimizing room allocations, reduction/monitor in energy misuse during OFF Hours, eg Hotels
nPassword protection for setup parameters
nLow PT, CT Burden
nSite Programmable CT, PT ratio (Pri & Sec) – easy ordering & Logistics
nUser Selectable Default Display Page
nCT reversal: auto-correction for Energy Integration in star (Wye) mode
nThe dual source energy meter has two integrators with user programmable names. You can program the alpha-numeric source names for these integrators from A to Y (except X) and 0 to 9. The factory-set names for these integrators are U and G
nDemand measurement (optional) for selected parameters
nMeter is equipped with an energy integrator function which provides several parameters for energy management: Wh.U, ON.U, Wh.G, ON.G, t.Wh, t.On.h and OLD registers
