Balmar 96 Series 48-volt Alternators

The 96-Series Alternators from Balmar establish a new standard for emerging 48V battery banks and inverter systems.

  • 60A (2.9kW) and 100A (4.8kW) at 48 Volts!
  • Industry Best Turn-on Thresholds
  • Low Power Take-Off at Idle Speeed
  • Designed for External Regulation
  • Works with the New Balmar MC-620 Regulator
  • Ideal for 48V Lithium Battery Bank

When paired with the New MC-620 Regulator, now you can combine the advantages of Balmar’s legendary multi-stage regulation capability in a 48V charging system. Offered in two power packages of 60A and 100A, these high power alternators provide 2.9kW and 4.8kW of charging power, respectively.

48V systems fill the need for ever-increasing power requirements from DC battery systems. DC Air Conditioning and Cooking, for example can stretch 12V and 24V systems beyond practical application. The benefits of a 48V system include much more efficient components such as chargers and inverters, manageable cable sizes, and of course higher output alternators in reasonable package sizes. Lithium batteries can be charged at very high rates, so a 48V system can accomplish this in a cost effective way.  With much lower cut-in speeds than the competition (1,325 RPM for 60A and 2,200 RPM for 100A) the Balmar 96-Series makes more power at lower RPM, thereby limiting the need for complex pulley schemes or over-throttling the engine at idle.

For lithium battery applications, the MC-620 regulator will disable charging for battery temperatures at or below 0oC (32oF).  The MC-TS-A and MC-TS-B temperature sensors are both required for lithium battery charging.

(1) Balmar’s 96-Series 48V Alternators are designed to be used with the MC-620 Multi-Stage Regulator.
Important: The MC-620 Regulator requires a 12V input, consuming up to 20A at 12V to power the device. It cannot be powered from a 48V source.

Alternator Output Curves

Alternator output is dependent upon a number of factors: battery condition and capacity, wire size, engine horsepower and RPM, battery temperature and alternator temperature. Of these factors, alternator speed and temperature are most important. The following graph describes alternator output based ambient (30oC) conditions where the alternator dwells at a specific RPM until the temperature stabilises. Test voltages are set at 13.5V.
