49. Vanner MBBM™ assures that the low voltage batteries stay at the optimum SOH throughout their entire life cycle. Low voltage battery life is extended.

50. Combining the Vann-Bus Equalizer with MBBM and the HBA also allows access to the low voltage battery power in extreme conditions … EXPERIENCE POWER… EXPERIENCE VANNER. ISO9001 / TS-16949 Certified

52. Does not overcharge the low voltage batteries

53. Temperature compensation

54. Communicates with MUX and Telemetry systems

55. J-1939 CAN Bus communication

56. “Real-time” Fault Notification

57. Event Recording and Prognostics

58. The CAN communication between the HBA and Vann-Bus Equalizer allows the low voltage batteries to provide power in addition to the HBA output, for extreme loads, for short periods

59. The CAN communication assures that the low voltage batteries will be recharged quickly for the next extreme power cycle. HBA HV DC Converter Vann-Bus Equalizer EXPERIENCE POWER… EXPERIENCE VANNER. ISO9001 / TS-16949 Certified

60. Total System Power Management & Control Unlike alternators the Vann-Bus Power Management System is able to control and adjust the low voltage battery charging at start-up. The spike in power circled is the result of the alternator “dumping” energy into partially discharged batteries at start-up. The Vann-Bus equalizer adjusts the HBA output to control the battery recharging, improves battery life, and reduces unnecessary energy use.
