Nexus UPS™ Series

The Bantam Vanguard 300 Series delivers professional-grade power conditioning and surge protection for the everyday electronics your work depends on: workstations, AV components, network and point-of-sale equipment, and sensitive office systems. It brings the same patented series-mode protection found across the Vanguard line in a compact enclosure sized for standard loads, available in two-outlet and four-outlet configurations. Our professional-grade power conditioning with superior surge protection is built for business and home-office professionals whose livelihood and reputation depend on high-quality, high-performance systems that demand safe, clean power. This is not a consumer-grade surge protector meant to "sort-of" protect inexpensive electronics.  

Why Choose the Vanguard™ 300?

• Vanguard is a complete power conditioner.
• Absorbs energy spikes, flickers, jolts, and surges traveling down business or home power wiring before they damage your investment.
• Does not dump harmful energy to ground the way consumer surge protectors do; Vanguard maintains a stable ground reference that digital equipment depends on.
• Filters EMI and RFI interference such as noise, flicker, hum, crackle, and harmful frequencies traveling along business and home power wiring.
• Suppresses power-line emissions (PLE): unwanted high-frequency signals that ride along power wiring, blocking them bi-directionally so they neither leak off your equipment nor couple onto it from the line.
• Provides bi-directional harmonic attenuation, dampening harmful harmonic power waves that typical electronic equipment generates and shares through power wiring.
• Improves power factor in digital equipment, increasing efficiency and reducing energy consumption and expense.
• Series-mode surge suppression that does not wear out, switch off, or stop protecting your investment.
• Backed by a lifetime, unconditional replacement warranty.
• A single-phase power conditioner and Surge Protective Device (SPD).
• Features harmonics filtration and power factor correction.
• Prevents "surge coupling" across all wires with its patented circuit.
• Intended for installation closest to the point of use.

Bantam Vanguard is professional grade for your important electronics; everything else is just consumer grade.

Electrical Features

• Input connection: 6 ft (1.8 m) SJTOW 105°C 14 AWG cord set, molded NEMA 5-15P plug.
• Output connection: two (2) or four (4) filtered NEMA 5-15R black outlets, depending on model.
• All outlets capable of up to 100 dB filtration on Line and Neutral, with 60 dB filtered ground and maximum surge suppression.
• Circuit overload protection provided by a 3 amp thermal breaker, push-to-reset.

Electrical Ratings

• Input voltage range: 110-120 VAC single phase.
• Output voltage and current: 110-120 VAC single phase, 3 amp.

Performance Metrics

• Voltage Protection Rating: 330 volts Line-Neutral, Line-Ground, Neutral-Ground.
• Electrical Mode Protection: patented in-series Normal (L-N) and Common Mode (L-G, N-G, L,N,G).
• Harmonic Attenuation: 40% typical reduction of odd-numbered current harmonics.
• Power Factor Correction: up to 30% average improvement.
• EMI/RFI Filtration: each path (Line, Neutral, Ground) bi-directionally filtered (patented).
• Noise Attenuation: up to 100 dB reduction on Line and Neutral, up to 60 dB on Ground; range of 100 Hz to less than 1 GHz.
• Electromagnetic Pulse Reduction: blocks unwanted pulse current from entering Line, Neutral, and Ground.
• Surge Energy Suppression: series-mode protection provides unlimited joule suppression.
• Duty Cycle: independently tested to retain full performance after a continuous 24-hour surge test, with no degradation to the unit or attached load.
• Actual Clamping Voltage: Line-Neutral 120V RMS +/-10V surge (typical); under load, Neutral-Ground 0V RMS +/-10V surge, line current less than 0.0001 amps over RMS.
• Surge Withstand Rating: withstood a 6000V / 3000A combination wave (1.2/50 µs voltage, 8/20 µs current) applied approximately every 45 seconds, matching the surge generator's recovery and recharge interval, across a continuous 24-hour period, with no degradation to the device or connected load.
