Collective digital earth leakage detection device LSG-210
Hikari Shoko Co., Ltd.
About This Product
■JIS C 8374 earth leakage relay compliant product
Significantly lighter and smaller than conventional models. The LSG-205W allows two-stage detection of light leakage and heavy earth leakage for up to 5 circuits.
■About this product
This product provides earth leakage protection in low-voltage AC power lines and is used in combination with a zero-phase current transformer. If a leakage occurs in the load side circuit after the zero-phase current transformer is installed, an electromotive force will be generated at the secondary terminal of the zero-phase current transformer. This secondary output is compared with an integer value in the detection circuit, and when the operating point is reached, the earth leakage display and output contact operate.
■Measurement display function
You can display the current value and maximum value of the measured value Io of each circuit. The display can be switched manually or automatically using the "circuit changeover" switch. The automatic display automatically switches the current value of each circuit at 5 second intervals.
■Transmission function using EIA-485
Measured values (current value, maximum value), contact information (output contacts), and abnormality information (error display) can be transmitted.
■Others
・Self-diagnosis function
If there is an error with this product, "Err" will be displayed on the measurement display. The “Circuit” indicator light (yellow) for each faulty circuit will flash. It will automatically return when things return to normal.
・Harmonic countermeasure products
・AC/DC shared free power supply
AC corresponds to AC80V to 240V, and DC corresponds to DC80 to 143V.
■Features
・Protects low-voltage circuit equipment from electrical leakage.
・Can detect up to 10 circuits.
・You can check the current value and maximum value using the measurement display function.
・Uses free power supply.
・It is a harmonic countermeasure product.
・Compliant with "JIS C 8374 Earth Leakage Relay".
