EMMA 6kW Single Phase Power Diversion

EMMA 4G SP15/30

The EMMA 4G SP15/30 is a cascaded load EMMA which has one Power Throttle and 1 Solid State Relay giving up to 6kW of power to resistive heating loads.

The unit is supplied with:

  • 1 EMMA 4G Control Hub with built in boost button
  • 1 EMMA Power Throttle
  • 1 Temperature Sensor
  • 1 Solid State Relay
  • 2 no. 50 Amp RMS Current Transducers (Can be larger if specified on larger generation or household load)
  • 3 Year Gaurantee

The unit is not supplied with as standard but may require:

  • 1 Power Transducer (not an AC transducer) which is used to determine power factor on Asynchronous turbines and some inverters with poor power factor.
  • 1 Store/Alternate R20 Schrack Relay which is used to switch from the normal heat store to an alternative heat store in export mode and is driven through the EMMA 4G unit via the 24V AC Transformer.
  • 1 240V to 24V AC transformer to drive the Store/Alternate load Relay described above.

6kW Energy & Micro-Gen Manager

The SP15 4.0G can divert up to 6kW of power to resistive heating.


LEM RMS Current Transducer datasheet

Our older range of LEM CT's ranged in size from 20Amp to 150Amp RMS current measurment with an aperature diameter of 16mm.


HQ Sensing RMS 0 - 10VDC CT data sheet

Our HQ Sensing CT's range in current measurement from 100Amps to 500Amps with Aperatures of 16mm to 36mm in diameter to fit from domestic to industrial scale needs.


Schrack Relay 20Amp DPDT data sheet.

The Schrack Dual Pole Dual Throw (DPDT) relay is used in EMMA systems where a stare and alternate load is available. the data sheet contains the extract of the data sheet relevant to the R20 which is used for switch over function of the EMMA system if it is part of the install.


Standard EMMA CT Placement Schematic

This schematic describes where to put the RMS CT's for a standard EMMA system.


Distribution Board Wiring

Schematic detailing the correct placement of CT's for a 4G EMMA system. NOTE: This does not apply to the ELITE.


HW Temp Sensor Installation Guide

If your tank doesn't have a probe pocket the following procedure can be used to fit a temp sensor to a tank.


SSR Dimensioned Drawing

The SSR (Solid State Relay) dimensioned drawing describes the size of the SSR for installation purposes and also demonstrates how it is wired.


Power Factor Transducer on EMMA

This Schematic shows how an ELtime Power Transducer is wired up with an EMMA system. This item is not dispatched as standard and is normally recommend by Cool Power Products for particular types of renewable plant.

ELITE Control

The ELITE is the latest addition to the EMMA product family. While we consider it to be the Elite of power diversion and monitoring it is in fact EMMA's little sibling or as we call it EMMA lite.
