ELECTRONIC LOAD MONITORING, 18 A, 24 V DC | AMG ELM-18

Weidmüller maxGUARD AMG ELM-18 is a single-channel electronic load monitoring module rated 18 A with an adjustable trip current, the highest-current module in the maxGUARD ELM range. It also allows by far the largest capacitive load of the range at 50,000 µF, which makes it the variant to use for heavy switched-mode loads, large DC-DC converters or drive control supplies that would nuisance-trip a smaller module on inrush.

• Rated current: 18 A, adjustable on the module
• Channels: 1 output channel, 4 terminals (++ / −−)
• Supply voltage: 24 V DC nominal, 18 V DC to 30 V DC operating range
• Trip behaviour: overload and short-circuit disconnection to the published characteristic curve; trip current and trip characteristic both adjustable
• Switch-on delay: 1 s
• Maximum load capacitance: 50,000 µF (50 mF)
• Pre-warning: I out > 90 % of set rated current, indicated by flashing green LED
• LED indication: green for healthy operation; red for switched off, flashing red for tripped, fast-flashing red for internal fault
• Reset: manual, via the front function key (activation time < 3 s for reset / ON)
• Connection system: PUSH IN, 0.14 mm² to 2.5 mm²
• Width: 12.2 mm
• Dimensions (W x H x D): 12.2 x 125 x 96.5 mm
• Mounting: TS 35 DIN rail; cross-connectable with maxGUARD potential distribution terminals to build a combined load monitoring and distribution station
• Operating temperature: −25 °C to +70 °C
• Protection degree: IP20
• Approvals: cULus (file E258476), RoHS compliant
• Order number: 2859800000
