The Balmar ARS-5H:
The Balmar ARS-5H represents one of the best values in a high performance external voltage regulator. Why? CUSTOM PROGRAMMING! There is almost nothing in the ARS-5H that can't be tweaked and I strongly advise taking advantage of these excellent programming features.

The ARS-5H replaced the venerable ARS-4H. The ARS-5H features an easier to program user interface, a faster processor and an all new adaptive alternator temp sensing circuit.

Adaptive Alternator Temp Sensing - AATC:

When the optional alternator temp sensor is used (MC-TS-A) the ARS-5H will find the maximum output the alternator can safely run at, for the surrounding ambient temps, and the demand being placed on it. Other external regulators simply cut the alternator current by 50% or by 100%, when they are over heating. As such competitors regulators will ping-pong back and forth off the high temperature limit;

100% Output > Drop to 0% > Back to 100% > Drop to 0%, on and on and on


100% Output > Drop to 50% > Back to 100% > Drop to 50%, on and on and on

This antiquated method of temp sensing used by Balmar's competitors digs into your alternator output performance and becomes very, very annoying. In contrast, the ARS-5H's processor decreases alternator current in small increments until the optimum output is attained to maintain the alternator temperature at the maximum safe level.

As the alternator cools or batteries accepted current drops off the output increases in 5% steps to maintain the highest output possible at all times. Balmar's Adaptive Alternator Temp Compensation (AATC) means you get the fastest possible charging the alternator can produce for the demand and environment at all times. Balmar is the only external regulator manufacturer to feature Adaptive Alternator Temperature Compensation.

Belt Manager (Formerly Called Amp Manager):

Only Balmar regulators allow you to set the maximum field potential for current limiting the alternator. This allow for better alternator cooling, longer alternator life or to work around belt constraints. Balmar's Belt Manager is really one of the most useful features you'll find in an external regulator.

For instance, if you want to upgrade your alternator but can't afford the serpentine conversion right now, no problem buy that 165A alternator and simply reduce its output to handle your single 1/2" belt. When you finally install your pulley kit revert to a higher alternator output. Balmar's Belt Manger can do this, the competitors can't. Do you want to maximize alternator life because you sail or venture far off the grid? No problem, buy the next size up alternator and reduce its maximum potential by 10%, 20% or more & your alternator will barely break a sweat and live a very long and happy life.

Remote Voltage Sensing:

The ARS-5H can be configured/wired for accurate voltage sensing so it can sense the actual delivered voltage at the batteries as opposed to the back of the alternator. When the regulator negative and regulator B+ wires are fed directly to the bank being charged, charging performance can be increased by 20%-40% or more when compared to self sensed alternators. Voltage sensing at the battery banks terminals allows the regulator to compensate for voltage drop between the back of the alternator and the battery bank.
