Flexible blackout prevention options

Designed for flexibility and efficient blackout prevention, the AGC 150 ATS includes an

Overlap feature that prevents blackouts during source switching by keeping the breakers

of both sources closed for a user-defined period and enabling short-time paralleling.

You can prioritise sources using parameters or digital inputs, offline or online, and you

can prioritise one of the connected sources, let the controller prioritise a source randomly,

or prioritise both in a three-breaker setup.

Two or three breakers supported

The AGC 150 ATS can control two or three breakers, allowing you to open and close a bus

tie breaker between the two power sources if needed. The controller can therefore be

configured for use in virtually any ATS application, anywhere in the world, including

the use of two sources simultaneously.

Easy setup and operation

You can easily configure the AGC 150 ATS for your application by adjusting its built-in

parameters or by using the M-Logic feature in DEIF’s free USW-3 utility software.

The sunlight readable LCD provides easy setup and quick access to important information.

On-screen text can be displayed in 8 languages, and the illuminated buttons smoothly

guide the operator and make the controller very easy and intuitive to operate.

Streamline power transfer with DEIF’s AGC 150 ATS controller

Ideal for emergency power applications with any power source, the AGC 150 ATS

is a robust, flexible, and user-friendly ATS controller that can operate up to three breakers.

The AGC 150 ATS is a dedicated automatic transfer switch (ATS) controller capable

of handling any type of power source. Its flexible setup options let you use it in a

wide range of emergency power solutions by controlling up to three breakers.

The IP65 certified front-mounted controller is easy to install, set up, and use.

Any power source in Source-Source mode

In addition to Generator-Mains mode (operating the ATS to switch between a mains

incomer and a genset), the AGC 150 ATS can operate in Source-Source mode,

accepting any kind of power source (for example two mains incomers, or a combination

of mains or a genset with a battery energy storage system or a renewable power source).

The controller can send start and stop signals to both sources.

Many operating options

The AGC 150 ATS uses automatic mains failure (AMF) logic and control signals defined

by the controller’s input/output settings to operate the ATS. For example, it can monitor

a mains source for voltage, frequency, and voltage anomalies, switching to the secondary

source in case of issues (after sending a start signal and checking that the voltage from

the secondary source is within the defined limits, if needed).

AGC 150 ATS: Advanced Generator Transfer Switch for Seamless Power Management

The AGC 150 ATS is an advanced generator transfer switch controller that ensures seamless

power transfer between multiple sources. Whether you are switching between mains and

genset, or integrating renewable energy sources, the AGC 150 ATS provides reliable and

efficient control. Its automatic mains failure (AMF) logic and flexible setup options make

it ideal for emergency power solutions. With features like blackout prevention through the

Overlap function and support for up to three breakers, this controller is designed to meet

the needs of any power management system. Easy installation and operation, combined

with multilingual support and a sunlight-readable LCD, make the AGC 150 ATS a top choice

for OEMs and system designer.

Increased step load performance

Compared to analogue AVR’s, DEIF’s digital AVR handles larger load-steps within

the same frequency/voltage boundaries. Typically, the gensets will accept 10%

additional nominal load. The embedded help features increase performance.

The DVC 550 has no mechanical moving parts that regularly need replacement

meaning less downtime, less service cost and more effective regulation.

Fast backup for critical power applications

If connected to an  AGC-4 Mk II controller, the DVC 550 can (depending on how

fast the engine starts) synchronise multiple gensets within six seconds thanks to

DEIF’s unique close before excitation-feature (run-up synchronisation). 

Critical power applications, in particular, will benefit from the improved control,

increasing safety and allowing faster start-up.

Dehumidify and dry your genset with integrated ventilation functions

Condensation build-up during idle time is a common problem in tropical climates.

Use the genset ventilation mode to prevent condensation forming on the windings

by removing built-up humid air using the alternator fan. Power generation is postponed

until the humidity levels are safe. Condensation on the windings can be removed using

the genset drying mode. During drying mode heat generated from a controlled internal

circulating in the alternator winding is used to evaporate condensation on the windings.

The genset will be connected to the busbar when it is safe to do so.

DVC 550 is a digital AVR designed for alternators with SHUNT, AREP or PMG excitation.

The voltage controller monitors and regulates the alternator output voltage.

Automatic voltage control

The DVC 550 is a digital automatic voltage regulator, which monitors and regulates

the alternator output with rated field current up to 7 A and up to 277V AC

The controller includes several protections and functions to keep the alternator

running in full safe operation.

The DVC 550 controller can improve genset performance, delivering up to a 10%

increase of normal load impact capability and is suitable for any application in the

critical power, IPP and rental segments.

Optimise generator size

Due to high inrush currents during start-up, generators for electric motor starting

and transformer magnetisation are often oversized by up to 200%.

Featuring inductive motor starting and magnetisation boosting, DEIF’s DVC 550

reduces oversizing requirements to a minimum and thereby save capital cost.

meaning less downtime, less service cost and more effective regulation.

Perfect solution for grid code compliance

The DVC 550 fast reaction speed complies with European grid codes, including German

VDE 4110/4105 standards. By combining the quick reaction speed with the AGC controller,

it is easy to comply with advanced grid codes (for example, low voltage ride through).

Achieve Precision with Automatic Voltage Control

The DVC 550 Digital Voltage Controller is designed to provide precise automatic voltage

control for alternators with SHUNT, AREP, or PMG excitation. This advanced controller

monitors and regulates the alternator output, ensuring stable and reliable performance.

With rated field current up to 7 A and up to 277V AC, the DVC 550 includes several

protections and functions to keep your alternator running safely and efficiently.

Maximum control with an integrated genset controller solution

The DVC 550’s built-in J1939 based communication offers an exclusive communication

channel to DEIF’s advanced controllers. Providing a high number of alternator data for

display, broadcast or predictive maintenance, the J1939 built-in communication is unique

on the market. You can quickly swap between nominal voltage and or frequency setting

 for a generator. Using CAN bus-based communication for voltage regulation reduces

the potential number of failure sources.

Use the DVC 550 together with the AGC-4 Mk II controller to maximise your benefits.
