DKM-260
DESCRIPTION
The DKM-260 is a precision instrument
designed for monitoring the status of earth
leakage in a DC supply busbar. It also
measures, displays and remote monitors
various DC parameters of a DC distribution
box.
The unit features a 32-bit ARM core
microcontroller.
The unit is supplied from the busbar voltage.
It accepts from 19 to 150VDC busbar
voltage.
The current input of the unit is isolated from
the rest of the circuit and has different circuit
options:
● External current shunt (standard)
● Internal current shunt
● Hall Effect sensor input
The relay output is programmable for its
function.
Thanks to its isolated RS-485 Modbus RTU
comport, the device is free from ground
potential difference issues and data are
safely transferred to automation and
monitoring systems. Program parameters
may be uploaded to the unit through the RS-
485 port.
