Features of 4000 Series Energy Meters

• Simple kWh parameter monitoring can be achieved  with the WL4000 or WC4000 series.
• The meter offers site selectivity of kWh or kVAh in addition to site selectivity for kWh or kVA or W or PF thus making it easier for inventory management.
• Parameters: Site selectable kWh / kVA / PF / W, Old energy
• Input voltage measurement range 50-520V AC (P-P)
• Accuracy Class 1 as per IEC 62053-21 and Class 0.5 as per IEC 62053-22
• True RMS measurement
• Simultaneous sampling of Volts & Amps
• Positive energy accumulation even with CT polarity reversal, reverse lock programmable
• User programmable password protection
• Auto scrolling
• Auto-scaling of Kilo, Mega, Giga values
• CT secondary site selectable 1A / 5A
• Low PT, CT burden
• Programmable PT, CT ratio
• Flush mounting 96 x 96 mm
• Site selectable for 3 Phase 4 wire, 3 Phase 3 wire, 1 phase
• Old register to store the previously cleared energy value
• Wide operating range of 80 to 300V AC/DC auxiliary supply
