| Discharge Voltage Resolution | 0.1V |
| Discharge Current Set | 1-200A |
| Discharge Time Set | 1m-99h59m |
| Discharge Capacity Set | 1-9999Ah |
| Current Adjust Resolution | 0.1A |
| Constant Current Control Resolution | 1% |
| Auxiliary Power Supply | 1-Phase 240V, 50Hz |
| Constant Current Discharge Control Accuracy | ±(0.3%+0.2A) |
| Cooling | Air cooled |
| Ambient Temperature | -10°C to +50°C |

The ZNF48V-200A is designed for battery discharging and testing systems. It allows operations at a nominal voltage of 48VDC and supports current adjustments from 1A up to 200A, making it ideal for telecommunications, marine power, and utility backup testing.
Yes, the load bank can discharge within a voltage span of 2V to 60V. However, to maintain the maximum 200A discharge current for long periods, the voltage should ideally be kept within 48V±10%. Outside of this range, the current will adjust downwards based on Ohm's Law.
This load bank is manufactured under strict quality standards and holds ISO9001:2008 Quality Certificates, alongside specific marine industry certifications such as CCS (China Classification Society).
The unit uses an active air-cooled cooling system. It is designed to run safely within ambient temperatures ranging from -10°C to +50°C, ensuring internal components are kept within thermal parameters during heavy discharge cycles.
We provide comprehensive pre-sales consultation and structured instruction manuals. If on-site setup is needed, professional technical staff can be dispatched to assist customers with installation, system debugging, and basic staff training.
