NH Research NHR 4300 16-Slot DC Electronic Load Chassis
The NH Research (NHR) 4300 is a 16-slot modular DC electronic load mainframe. It houses load modules such as the 4312 (120 V) and 4350 (500 V) units. The chassis also accepts the 4301 power analyzer module for added measurement capability. Together these modules create a configurable multi-channel load test system for automated testing. The model delivers a maximum power rating of 2400 watts total. Its enclosure measures 8.75 by 19 by 22 inches in a 5U format. The fully loaded mainframe weighs 86 pounds including all of its installed modules. Each module mounts to the front panel and connects using four mounting screws. The waveform digitizing on this mainframe operates at a sampling rate of 1 MS/s. The record length extends to 256K points for each captured waveform measurement cycle. The voltage bandwidth spans DC to 500 kHz across the full measurement spectrum available. The current bandwidth spans DC to 100 kHz supporting accurate and dynamic load response testing.
The measurement accuracy on the NHR 4300 holds at 1 percent of reading value. The time accuracy remains within 0.05 percent of reading plus a single sample period. The trigger system responds to external triggers digital inputs and voltage level thresholds. The noise measurement bandwidth covers 10 Hz to 20 MHz with accuracy of 3 percent at 1 MHz. The peak-to-peak noise measurement on this unit spans a range of 0 to 2.5 VAC. The digital input timing ranges from 100 microseconds up to a maximum of 168 hours. The timing resolution reaches 100 nanoseconds and accuracy remains within 0.05 percent plus 100 microseconds.
This mainframe measures overshoot undershoot AC RMS and AC plus DC RMS values. It also captures positive peak negative peak and peak-to-peak voltage and current readings. The rise time fall time settling time and hold-up time are measured as well. The additional measured parameters include average power peak power trigger-in time and resistance readings.The operating modes on the NH Research 4300 Electronic Load Chassis include constant current constant voltage and constant power. The constant resistance mode and auto mode are also fully supported by the system. The system includes LED driver mode and solar PV panel testing with MPPT. The macro mode stores up to 1000 programmed settings enabling fully automated test sequences.
