Part of DEIF’s current transformer range, these measuring transformers

convert high current into lower nominal current value,

thus making it possible to use instruments and relays with standardised values of rated current.

DEIF offers various physical sizes of the measuring transformers.

The range is suitable for cables and several busbar combinations and positions.

In order to ensure short delivery time, we always keep transformers in stock.

Full compatibility with wide range of equipment

The ASC-4 Battery can communicate with a BCU (battery control unit) or directly

with a BMS (battery management system) and PCS (power control system) over Modbus,

allowing it to be used with a wide range of ESSes. It is designed for full compatibility

with DEIF controllers, allowing you to set up an EMS quickly and efficiently.

For an updated compatibility list for the controller, see Application Notes on the Documentation tab.

M-Logic provides flexibility and customisability

The setup of the ASC-4 Battery can quickly and easily be reconfigured as needed

using the user-friendly M-Logic tool (part of DEIF’s free PC utility software offering).

This allows the controller to be customised to a wide range of local applications.

Emulation feature provides safe system testing

The built-in emulation feature of the ASC-4 Battery enables you to interact with the

controller in a controlled and safe environment without risking to damage any equipment.

All you need to do to perform a complete test of your system is to turn on your controller and connect

communications.

Energy source, power source, or droop mode

The ASC-4 Battery is suitable for grid-forming or grid-following applications,

and it supports energy source or power source functions.

It is also able to run in droop mode (acting as a virtual synchronous generator)

if the ESS supports this. The ASC-4 Battery can switch operating modes

very quickly as required. It supports grid/power quality support with active

or reactive power, spinning reserve capability (reducing the number of gensets running),

frequency and load response, and load control.

Built-in power metering

The built-in power metering feature of the ASC-4 Battery measures busbar voltage,

current, and frequency before and after the breakers. Operation and mode switches

can be configured to be based on these readings, for example carrying out mode

switches based on voltage and frequency changes.

The ASC-4 Battery lets you quickly and easily add energy storage systems (ESS)

such as batteries in greenfield hybrid applications with other DEIF controllers,

providing seamless energy storage in commercial and industrial applications.

The DEIF ASC-4 Battery is a highly configurable sustainable energy storage

controller that allows seamless integration of an ESS in greenfield applications

with other DEIF controllers such as the AGC-4 Mk II advanced genset

controller and other sustainable controllers in our ASC-4 range.

Wide range of control strategies

The ASC-4 Battery lets you store and use green power from PV panels and wind turbines.

The controller handles charging and discharging as required by the operating scenario,

based on state of charge control of the ESS or using Schedular-Command timers

that allow you to define which sources to charge from, and when.

It includes control strategies such as peak shaving, load take-over, fixed power,

automatic mains failure (AMF), and mains power export (MPE), allowing it to be

used for a wide range of applications. You can define and change the priority of connected power

sources.

Power management applications

DEIF’s Power Management system fully integrates the sustainable power plant

and the genset plant into a unity. The ASC Plant Management is connected to

the CAN bus constituting the internal DEIF Power Management communication link.

For that reason, this approach is only applicable for plants equipped with AGC Plant Management

controllers.

Stand-alone applications

In stand-alone applications, the ASC Plant Management knows little about the

surrounding environment in which it is placed. Based on power readings and breaker positions,

the ASC Plant Management determines the power references to the sustainable power plant.

This approach is applicable for integrating sustainable power in already commissioned genset plants,

whether they are equipped with DEIF controllers or not. Stand-alone applications

support applications containing up to 16 gensets.

Plug’n’play HMI touch screen

For improved user-friendliness, we’ve even created a plug and play touch screen

display for hybrid projects. It’ll present all relevant data to you in real time,

for instance power metre and inverter readings, PV penetration/performance ratio and much, much more.

Spinning reserve

The ASC Plant Management offers spinning reserve support as a percentage of the produced power,

as part of an existing superior system (for instance an existing PLC system) or by means

of short-term cloud detection functionality, depending on your application and requirements.

Ideal for self-consumption applications

While in grid parallel mode, the ASC Plant Management is capable of feeding surplus PV

energy to the grid and generate profit in accordance with grip operator feed-in tariffs.

Alternatively, the ASC Plant Management can regulate the PV production to match the

self-consumption thereby preventing any feed-in of PV power

to the grid if prohibited by grid operator regulations.

Minimum genset load in island operation

Minimum genset load constraint is available in the ASC Plant Management.

The constraint applies in island operation only. This constraint will cause the

sustainable power penetration to decrease in case it is compromised.

This is to secure a certain amount of load on the gensets, eliminating the risk

of reverse power situations and impure combustion and exhaust problems.

Automatic sustainable controller, ASC Plant Management

Serving as a link between photovoltaic (PV) power plants and genset power plants,

DEIF’s Automatic Sustainable Controller (ASC Plant Management) is

a safe and reliable control solution for PV/genset hybrid plants.

Maximising sustainable power penetration

The ASC Plant Management will in any operation mode automatically maximise

sustainable power penetration, depending on the total load demand to

the hybrid without compromising constraints such as minimum genset load demand.

Same features as the master controller

The AGC 150 Remote Display gives you access to all of the features in the master

controller it is linked to, making remote configuration of controller parameters

as easy as using the master controller itself. The user-friendly display and menu

structure in 8 languages is the same as the rest of the AGC 150 series.

Configuration changes performed on the AGC 150 Remote Display are immediately

eflected on the master controller, and vice versa.

Flexible connection options

Installation and connection of the AGC 150 Remote Display is quick and easy.

The unit can be connected to its master controller over the local network through

an Ethernet switch or using a point-to-point cable connection, and the front-mounted

IP 65 classified enclosure is as easy to install as all other controllers in the series.
