The NH Research 9200 Battery Test System holds up to three 12 kW, 40, 120 or 600 V bi-directional loads. Systems can be configured utilizing from 1 to 12 modules. Each power module is isolated, independently programmable, sources & sinks current, regenerative, and contains an advanced digital measurement system. System software allows using these modules individually, in any combination or as one single group to meet battery test requirements. An NH Research 9200 system configured with 3 power modules can divide its resources--one of the modules could be testing a battery of 12 kW, while the other two modules could be paralleled to test a 24 kW battery. Both batteries could have different test programs and start/stop times. The end result is that this test system is an extraordinarily flexible tester that solves the challenge of matching test resources to a wide range of battery power, test program and duration requirements. In this manner, the NH Research 9200 Test System significantly increases the utilization of test systems and thereby lowers the cost of battery testing.
