Overview
SA2100 is a handheld multi-functional device which is designed to measure and analyze single or three-phase power system. This portable class S device can provide safe, convenient and accurate measurements for troubleshooting power networks.
SA2100 Portable Power Quality Meters
Portable Power Quality Meters enable electricians and facility maintenance professionals to troubleshoot and benchmark power quality problems over time. They help you identify energy waste in your facility and detect and prevent power problems before they occur.
Why do you need Power quality meter analyzer?
Portable Power Quality Meter identifies power quality problems that often manifest themselves as dips, spikes, harmonic distortion, imbalances, flicker and transients.
Power quality determines the suitability of electrical energy to drive motors, machines and other end-user equipment.
Poor power quality can affect the ability of these devices to operate properly, which can lead to malfunctions, premature failures or possibly cause them to not work at all.
Most power quality analyzers monitor total harmonic distortion, phase angle, power factor, balance, etc. to get a complete picture of the system.
Laser Source Power Meter
The Laser Source Power Meter provides an economical, stable laser source for point-to-point attenuation measurements. It features a rugged design that withstands the harsh test environments of fiber optic cable installation and maintenance.
Automatic Constant Feed Speed Control: Automatic output voltage adjustment in real-time to ensure constant preset feed speed regardless of weight change of the workpieces.
Automatic Resonant Frequency Search: Search out and output the resonant frequency of the load. other related parameters are also set automatically
Rs485 Communication: All parameters of the controller can be adjusted via R485.
Sync Output: Sync the output waveform of the slave controller with that of the master controller to the same frequency and phase to avoid beat effect
Digital Overheat Protection: If the internal temperature of the controller gets too high, the controller will stop its output to protect itself.
Overcurrent Protection: If output current exceeds its rated value the controller will stop its output to protect itself and the load.
Restorable Short Circuit Protection: If the controller's output is short-circuited, it will shut down its production to protect itself and the load. But the fuse inside will not be blown. So when there is no short circuit at the output side, the controller will work again after power is on.
