DKM-430-PRO MULTIPLE NETWORK ANALYSER • EQUIVALENT TO 10 ANALYSERS • 1MB RECORD MEMORY • 30 x CT INPUTS • 24xFUSE DETECTORS • HARMONIC ANALYSIS • INTERNAL GPRS MODEM (OPTIONAL) DKM-430-PRO is a precision instrument allowing the measurement, recording and remote monitoring of 10 3-phased or 30 single-phased feeders (or any combination of these two) in AC distribution panels. The unit offers additional 24 inputs capable of being used as FUSE detectors or digital inputs. Several combination of these two are available. The optional internal GPRS modem allows remote monitoring and control of the distribution panel without the use of any additional module. The standard model has universal 85-300VAC supply. 24-110VDC supply versions are available. Current inputs of the unit are designed for 0.1A output current transformers (CTs). Each CT can be assigned to any phase voltage and any virtual analyser. Inputs can be moved between analysers without modifying connections. The astronomical relay function calculates sunrise and sunset times precisely for daylight based applications. Any fault or warning signal can be connected to digital inputs of the unit. Input functions are selected from list. Any function can be assigned to relay outputs of the unit. Relays may be remotely operated through the central monitoring program. Additional 24 inputs are optional. The isolated RS-485 MODBUS RTU data port is unaffected by ground potential differences and allows safe transmission of information to monitoring and automation systems.
