UWP-DLB overview

UWP-DLB is a local controller for the dynamic load management (DLM) of EV chargers.

It is designed to be installed onsite, local to the EV chargers, where it:

  • Monitors OCPP messages relating to charging limits

  • Monitors energy use on-site using a meter using TCP/RS485 (optional)

  • Automatically adjusts the EV charger limits so that the load is balanced to the site

  • Works with single and three phase systems

  • Works with AC and/or DC chargers

  • UWP-DLB can be configured locally or remotely using its website interface

  • Support for whitelists of RFIDs (when used without a CSMS)

  • Downloading of transactions is now supported in CSV and NEM12 format

  • Supports grouping of chargers for separate cable run limits, and priority channels

  • Network proxy allows access to configure other 3rd party IP devices using UWP-DLB

UWP-DLB is designed to be used in two scenarios:

  • Online: As a local load balancer, authorizing transactions through a cloud-based charge station management system (CSMS). Provides backup of transactions in the event of an internet outage.

  • Offline: As a local load balancer with local authorization. In this mode RFID tags whitelist are used.
