  1. PowerLogic Branch Circuit Power Meter (BCPM) Need monitoring at each branch circuit?

  2. PowerLogic BCPM The BCPM monitors a complete Power Distribution Unit (PDU) • CT strips monitor the circuits • Monitor 84 circuits with a single BCPM • Auxiliary inputs monitor the mains • Two inputs for auxiliary CTs (3-phase, 4 wire) • Auxiliary CTs ordered separately

  3. Comparison: BCM and BCPM

  4. Product Selection Guidance:Branch Current Monitor (BCM) and Branch Circuit Power Meter (BCPM) Select the BCPM for the following: • Power and energy measurements at either the branch circuit or mains level • Power, energy or current measurements on 84 branch circuits with a single device • Current, energy or power measurements on the mains • Advanced alarming capabilities, including trip alarms and user-defined thresholds for high-high, high, low and low-low alarms • Accurate measurements at low current levels, down to ¼ A, on each branch circuit • Select the BCM for the following: • Current only measurements on 42 branch circuits • Simple alarming, including high and high-high alarm levels • Need a split –core CT option

  5. BCPM does the work of an MCM + BCM • Auxiliary (mains) metering • Auxiliary metering is equivalent that of the MCM • Two 3 phase, 4 wire auxillary inputs • 1/3 V output CTs • Auxillary CT’s ordered separately Circuit metering: • Two or four CT strips with 21 channels per strip • Max Current: 100 A CTs

  6. BCPM Accuracy • Auxillary metering: • Current: 2% of reading from 1-10% of rated current; 1% from 10-100% of rated current • Voltage: 1% of reading from 90 to 277 V, Line to Neutral • Circuit metering: 0.25 A to 2 A2 A to 100 A Current: 3% of reading 2% of reading Energy: 4% of reading 3% of reading

  7. New Measurements on the BCPM Key Measurements: • Energy • Real Power per phase • Power Factor • Total • Per phase • Voltage • Line to line and average L-L of 3 phases • Line to neutral and average L-N of 3 phases • Current per phase • Frequency (Phase A)

BCPM ApplicationsDesigned for data centers and critical power operations • The BCPM provides data center managers with information that allows them to: • Maximize uptime and avoid outages • Efficiently use existing infrastructure • Effectively plan future infrastructure needs • Simply and easily allocate costs

  12. BCPM Application Maximize uptime and avoid outages • The BCPM advanced alarming capabilities provide alerts before a breaker trip occurs • High-high, high, low and low-low alarm levels • Set alarm levels as a percent of breaker rating to ensure advanced notice of potential issues • The BCPM uses modbus communication to easily integrate into your existing monitoring network

  13. BCPM ApplicationEfficiently use existing infrastructure • The BCPM provides you information on energy use at the circuit level • Track infrastructure usage levels • Adjust circuit loading to distribute load • Avoid capital cost investments by maximizing usage of existing infrastructure

  14. BCPM ApplicationEffectively plan future infrastructure needs • The BCPM can provide historical usage data, to ensure that new infrastructure projects are sized correctly • Track usage at the circuit level • Develop reports on historical usage patterns • Use reporting to accurately predict future needs • Create infrastructure projects that are appropriately • sized

  15. BCPM ApplicationSimply and easily allocate costs • Use accurate energy consumption data to allocate costs • Track usage patterns and determine areas of potential savings • Create ongoing reporting structures to effectively manage costs

  16. BCPM Performance and Specifications • Specifications • Update rate: 1.2 sec. per panel board, 2.4 sec for aux inputs • Sampling Frequency: 2560 Hz • Frequency: 50/60 Hz • Overload capability: 10 k AIC • Input power: 90-277 V AC • Ribbon cable support: up to 20 ft • Operating temperature range: 0º - 60º C (<95% RH, non-condensing) • Storage temp. range: -40º C to 70º C • Standards and Safety • UL 508, “open type” device • Installation category: CAT III • IEC/EN 61010 CE

  19. BCPM Dimensions – CT strips

  20. BCPM installation configurations • The BCPM supports four configurations: • Top feed • Bottom feed • Inline odd/even • Inline sequential Configuration is set by the user as a Modbus register

  21. Single Row Sequential Single Row Odd/Even BCPM Installation Configurations

  22. BCPM Software Support The BCPM is supported in the following software: • Initial Setup and Configuration: • ION Setup • Ongoing Monitoring and Status: • PowerLogic System Manager Software (SMS) • Device driver • Optional device type downloadable from www.powerlogic.com • Software based alarms only • No device resets • PowerLogic ION Enterprise (ION E) Full device support • ION Vista support (real-time displays) • Default OPC support • Alarm notification • Automatic onboard data uploads (as supported by device) • Default metering parameter resets (as supported by device) • Default ION Reporter support

  23. Frequently asked questions • Can the new BCPM printed circuit board (PCB) be used to replace the old BCM PCB for a retrofit application? • No. The CT strips shipped with the BCPM are different from those used with the BCM and therefore wont work when interchanged. • What is the standard length of the ribbon cable shipped with the BCPM? • Three feet • Does the BCPM support various type breaker (single, 2 and 3 pole) in a single panel? • Yes, but this type of installation must be performed by PowerLogic Services due to the complex register mapping for this device.

  27. Two feature sets available: BCMS and BCMS Plus BCMS measures current only BCMS Plus adds voltage measurements and power and energy at the panel board level The BCMS and BCMS Plus do not monitor the mains current. They sum the branch breaker currents to report current per panelboard. CompetitionPDI BCMS and BCMS Plus - Measurements

  28. CompetitionPDI BCMS and BCMS Plus - continued • BCMS Plus differs from the BCPM in the following ways: • No No inputs for Mains CTs. The BCMS does not monitor mains current, but instead calculates total current by summing the individual current values for each breaker • The BCMS only reports power and demand values for the entire panel board, not per phase • The BCMS quotes 2% accuracy for measured current, but does not give an accuracy range Accuracy: Current – 2% or 0.1 Ampere, whichever is greatest • BCMS specification does not provide a range of current where it is accurate • PDI has suffered in the past from poor product quality and questionable accuracy • PDI makes hardware only and is not able to sell a system or end-to-end solution
