Phase
Single phase
Overview
Two families, chosen by how tightly the voltage must be held. Wise11 and WiseMP11 are microprocessor-controlled stabilisers using zero-current and zero-voltage crossing, from 8 to 50 kVA — Wise11 switches across four taps for a 220 Vac ±5% output, while WiseMP11 uses eight taps to hold ±2.5%. ECON is the small 2 kVA unit for sensitive single loads such as POS terminals, PABX systems, computers, security networks, medical refrigerators and laboratory freezers.
Key Features
- ✓Wise11 — 8 to 50 kVA (Wise0811 through Wise5011), holding 220 Vac ±5% across four taps
- ✓WiseMP11 — same ratings on eight taps, holding ±2.5% for loads that need a tighter voltage
- ✓ECON — the 2 kVA unit (ECON-2000-2 and ECON-2000P), over 97% efficient with under 0.2% THD
- ✓Taps change at zero current and zero voltage, so correcting the voltage injects no switching noise
- ✓Wide input window — Wise11 at 220 Vac +15%/−20%, WiseMP11 at +15%/−17.5%, ECON at +25%/−30%
- ✓Handles 150% overload for one minute and 1000% for a single cycle · 3:1 crest factor
- ✓Protects against surges, spikes, sags and brownouts, EMI/RFI line noise, overload and short circuit
- ✓LCD shows input and output voltage, frequency, current and % load, with analogue meters · optional RS-232 · operates 0 to 45°C
