    Diesel Engine Ratings.

    Thanks for the responses. I believe the genset has a 110 kW, prime rated, Stamford End as per the following: Surely, given the variable nature of the load and the fact that on average the load is between 35 kW - 40 kW with brief spikes up to 76 kW it would be more fuel efficient to have a...

    Diesel Engine Ratings.

    Hi All, I was wondering if somebody could help clarify the power ratings for a diesel generator for me. A vendor is trying to sell me this generator (I think it is all he has in stock...) and I am convinced that it is larger than what I require. I require a 80 kW prime generator to service a...

    Diesel Genset Engine - Torque Speed Curve

    Hi All, "Why? The engine will always run at (or close to) 1800 RPM". Well not necessarily that is why I posting the question. We are exploring the option of using the engine in a variable speed configuration whereby the synchronous alternator is decoupled from the load by a back-to-back power...

    Diesel Genset Engine - Torque Speed Curve

    Hi All, I am analysis the performance of a Generac SD250 diesel engine (https://www.generac.com/Industrial/products/diesel-generators/configured/250kw-diesel-generator. Using info from the attached data sheet - including the hourly fuel consumption figures (l/hr) - I have managed to calculate...

    Modbus Communication between EATON Power Meter and Accuenergy Data Acquisition Server

    Hi All, Thanks for all the responses. Things me quickly on here...Some of them came in late last night and I only got back on site this morning, at which point I was able to make some progress with the meter. Following the instructions from XNUKE above I have been able to read data from the...

    Modbus Communication between EATON Power Meter and Accuenergy Data Acquisition Server

    Hi xnuke, Thanks for that. So if I use 9FC3 as the stating address and I enter the count as 6. Does that mean that the "Watts, 3-Ph total" address should be 9FC3?

    Modbus Communication between EATON Power Meter and Accuenergy Data Acquisition Server

    Hi, I am able to communicate with the power meter if I connect it directly to a laptop and run the ICC Modbus master tool. So I don't think there is anything wrong with the serial link. I just can't get the Accuenergy Data Acquisition Server to talk to the meter. It's definitely something with...

    Modbus Communication between EATON Power Meter and Accuenergy Data Acquisition Server

    Hi All, I am using an Accuenergy Data Acquisition Server (https://www.accuenergy.com/products/aculink-810-data-acquisition-gateway-server/) to log data from a number of power meters. Each of the power meters communicates with the Accuenergy via Modbus RTU. I am having trouble getting the...

    Power Meter Parameters (EATON IQ100 Series)

    Hi, Sorry I did forget the attachment. I have added it. The CTs are at the Gen Breaker and there are no auxiliary loads. I'm guessing Whr-Delivered or Whr- Total would work...

    Power Meter Parameters (EATON IQ100 Series)

    Hi all, I was hoping somebody could help me understand the difference between the parameters being read from an EATON IQ 100 Power meter. I am putting together a Modbus template to poll various parameters from the meter. The Modbus map is attached. The site we the meter is installed is a...

    24 Volt DC UPS System

    Thanks Guys. itsmoked, that info is useful. The main thing that attracted me to the MEANWELL was the reasonable cost. LionelHutz I'm pretty sure the MEANWELL DRC-40B (described in the link) can be set up to provide a DC UPS system by adding a battery. It's clearly described in the datasheet...

    24 Volt DC UPS System

    Hi All, We have a number of data loggers deployed in the field recording data from various sensors. They all require 24 Volt DC power supplies and each draws about 950mA. To ensure that they keep running during interruptions to the mains I would like to connect them to a UPS. I have found a...

    Communicate to Modbus Power Meter (EATON IQ100) over Internet

    Thanks for the responses guys. The Chipkin device looks promising and appears to do what is required.

    Communicate to Modbus Power Meter (EATON IQ100) over Internet

    Hi All, I was hoping to get some advice on how I might communicate with an EATON IQ 100 power meter. The meter has an RS485 port and Modbus-RTU Protocol. The datasheet is attached if it helps. The meter is located in a generator room, unfortunately, there is no wifi or internet in that room...

    Microgrid Power Metering Options - EATON Meters

    Dear All, I was hoping to get some tips on metering devices that could be used to monitor and log energy consumption in a small (150 kW) microgrid. Eaton IQ 100/200 series meters have been recommended. This is a remote microgrid but internet and mobile signal is available on site. Ideally, we...
