Products | KET-PMT-247

Panel-mounted, three-phase power meter for current transformers

KET-PMT-247 is a panel-mounted energy meter for measuring energy and main electrical parameters in industrial and civil environments, with built-in RS485 ModBUS RTU communication.

It has 4 dry contact digital inputs, 2 relay outputs and 1 pulse output.

Interface with high-brightness LED/LCD display, parameter setting and push-button control, ideal for real-time energy monitoring systems. It can directly replace traditional power transmitters and measuring instruments.

The KET-PMT-247 can be used in all kinds of control systems, SCADA systems and energy management systems.
