AMF Controller Interface Module

1. INTRODUCTION

AMF-10R Interface Module is use to simplify wiring

in electrical operation and mechanical maintenance

transfer switch connecting to assorted brand AMF

Controller available on the worldwide Markets.

The module is built-in with full phase protection

fuses for Mains and Generator circuits. The

pluggable terminal block design makes the wiring

connection a whole lot easier and faster. Installer

only needs to connect to the correct control signal

terminal to complete the installation

The AMF-10R is compatible to all types of AMF

controllers available on the market, for example the

Kutai AMF-10, Lovato RGAM, Bernini BN series,

Deepsea DSE series and many more. The module

also provides connection for assorts of transferring

switches for example, the single motor driven

transfer switch (e.g. The Kutai MCCB type Basic

Transfer Switch), the twin motor driven transfer

switch (e.g. The Terasaki-MOT, Merlin Gerin-MCB)

and the Double Throw Solenoid switch (e.g. Aichi,

Takada and many more).

The AMF-10R module provides an adjustable

transfer countdown timer from 9~17sec adjusted via

a built in potentiometer. The timer starts the

countdown when the transfer switch is energized to

make the transfer. When the countdown is

completed, the module automatically cuts off the

launch (start) signal to prevent danger of repetition

power source transfer if the over-load or short-circuit

trip occurs.

AMF-10R allows wide range of operating power

inputs from 9 ~ 35VDC. The Installer can easily alter

the wiring connection and change the system

voltage from AC220V to AC380V without the use of

transformer. In addition, the module also offers

indication lighting output terminal to provide the

control panel with lighting indication of the power

source status

The Module is insulated with high anti-corrosion

UL94-V0 epoxy, suitable for use in the hostile

environment inside the genset control panel.
