EMMA 4G TP45/675 EC

EMMA 135kW Three Phase Power Diversion with Export Control

EMMA 4G TP45/675 with Export Control

The EMMA 4G TP45/675 with Export Control (EC) has three control hubs and three Power Throttles and 42 SSR's giving up to 135kW of power to resistive heating loads.

The unit is supplied with:

  • 3 EMMA 4G Control Hub with built in boost button
  • 3 EMMA Power Throttle
  • 3 Temperature Sensor
  • 42 SSR'S
  • 6 no. 250Amp RMS Current Transducers (Can be larger if specified on larger generation or household load)
  • 3 EMMA SSR Controllers
  • 3 Year Gaurantee

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

  • 1 Export Control Isolation Relay to open the connection of the renewable source (e.g Inverter) from the grid. This is also known as the GVS Isolation Relay.
  • 1 240V to 24V AC transformer to drive the Isolation Relay and possibly the Store/Alternate load Relay described above.

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

  • 1 or 3 Power Transducers (not an AC transducer) which is used to determine power factor on Asynchronous turbines and some inverters with poor power factor.
  • 1 EMMA Power Transducer Multiplexor where 1 power transduser is used on a balanced output system.
  • 45 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.
  • 3 R20 Schrack Relays to act as the signal for the G59 shutdown.

EMMA 4.0G Product Installation Manual

The EMMA Product Installation Manual contains all the information you need to complete a successful install of the EMMA System up to 18kW single phase and 54kW three phase.

EMMA 4G Operating Instructions

The EMMA 4G Operating Instructions contain all the end user needs to know for understanding the various screens of information and settings on the EMMA unit.

135kW 3 Phase Energy and Micro-Gen Manager with EC

The TP45/675 4.0G with Export control can divert up to 135kW of power to resistive heating through 45 x 3kW resistive heaters with fifteen on each phase.

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.

EMMA with Export Control

EMMA with EC allows for installs to have a greater renewable output than the Max Export Capacity (MEC) on site by diverting excess energy to heat.
