Users can set Over Voltage Protection (OVP), Over Current Protection (OCP), and Over Power Protection (OPP) for each channel. The system displays alarms when protection limits are exceeded.
The power supply operates in either Constant Voltage (CV) or Constant Current (CC) mode based on load impedance. Users can prioritize CV or CC mode depending on application requirements.
Users can set IP addresses, baud rates, beep sounds, and display language. The RS232 interface does not support flow control.
The N39200 supports RS232 and LAN communication interfaces. The document provides steps for setting up remote control via these interfaces, including setting baud rates and connecting multiple devices.
To enable remote control of the N39200 series power supply, configure the application software on a PC. Set the communication mode to LAN and ensure the IP address matches that of the N39200. Once connected, the device will enter remote control mode, disabling local operations. To revert to local control, press the 'Lock' button.
Regular maintenance involves cleaning the device with a dry or slightly damp cloth, ensuring the power is disconnected. For fault self-inspection, check power supply, device startup, fuse condition, connector integrity, system configuration, and device specifications. Calibration is recommended annually.
The N39200 series offers dual-channel programmable DC power supply with various models providing different voltage, current, and power specifications. Measurement accuracy is maintained under specific conditions, including a warm-up period of 30 minutes. The device supports LAN and RS232 interfaces and operates within specified environmental conditions.
The device includes several protection mechanisms such as over voltage (OVP), over current (OCP), over power (OPP), over temperature (OTP), and low voltage protection (LVP). Error alarms indicate power supply faults.
The N39200 series uses NGI's standard communication protocol with RS232 and LAN hardware interfaces. The RS232 interface supports multiple baud rates, while the LAN interface complies with IEEE 802.3 standards.
Recommended wire gauges are provided based on temperature conditions and rated current, ensuring safe and efficient operation.
Common issues include screen malfunction, no output, improper voltage/current settings, unstable output voltage, and high output voltage ripple. Solutions involve checking connections, adjusting settings, and avoiding electromagnetic interference.
