Overview
NHR 4700-6 DC Electronic Load Highlights
The NH Research (NHR) 4700-6 Programmable DC Electronic Load is designed for testing applications that require high-power and high-current as well as for dynamic performance measurement. The NHR 4700-6 Load, with its built-in capabilities, can rapidly generate engineering-characterization-like test information with excellent reliability, eliminating the need for separate external measurement instruments.
Remote Voltage Sense: 2 VDC max drop between sense and load input
Power-up self test of all major functions including status of input, output, control and protection circuits
Continuous checking of performance parameters and appropriate error messages and/or LED fault indicators when necessary
Protection: OP, OC, OV, OT, Reverse Voltage and Undervoltage Lockout
Trigger Output: Sychronizes external device to programmed load step
Trigger Input: Sychronizes programmed load step to an external device
Current Monitor: 0 - 10 V external signal appropriate to 100% current for the selected range
Analog Control: 0 - 10 V external signal appropriate to 100% current for the selected range
Automatic fan speed control for fan noise reduction
Sychronously controlled, actively power-balanced, and operate efficiently in parallel as a single load
Field Expandable with changes only to the input connections
High-resolution waveform capture for analysis of dynamic transients
18 built-in, precision voltage, current, power and timing measurements that eliminate additional dedicated measurement instruments
Isolated digital inputs and outputs for test fixture support
PC/LAN control using LabVIEW & IVI drivers
Optional touch-panel user interface
Auto Mode that provides glitch-free automatic switching between CR, CC, CV and CP limits
