NS Series Power Amplifier Overview
The NS Series Power Amplifier is designed for high power, low frequency applications, particularly in challenging industrial and military environments. Key features include:

• Models ranging from 3kW to 100kW
• High operating efficiency with 96% efficiency in Class D amplifiers
• Bandwidth of 200Hz to 4000Hz
• Solid state reliability and modular serviceability
• Built-in protection and shock mount options
• Operating temperature range from 0º C to 60º C
• MTBF greater than 100,000 hours

Robust Design and Maintenance
The NS Series is designed to meet MIL-STD environmental conditions, with features for easy maintenance and remote troubleshooting. It includes BITE (Built-In Test Equipment) and BIST (Built-In Self Test) capabilities to facilitate system testing and fault finding.

High Operating Efficiency
The amplifiers use Interleaved Pulse Duration Modulation (IPDM) to minimize high frequency distortions and reduce the size and weight of filter components.

Sophisticated Remote Control and Monitoring
The NS Series supports remote control and monitoring via IP and SNMP, allowing users to access status, controls, alarms, logs, and reports.

Grounding, EMI Shielding, and Safety
The amplifiers are designed to meet specific MIL-SPEC standards for EMI conditions and are marked for safety at all input and output locations.

Redundant Architecture
The NS Series features a fully parallel redundant architecture, ensuring no single point of failure. It includes redundant power amplifiers, digital and analog audio inputs, multiple fans, low voltage power supplies, and optional redundant exciters.

Fault Protection
The system is designed to handle various fault conditions, with software-controlled limits for different situations.

State-of-the-Art Digital Exciter
The digital exciter provides precise control of amplifier switching, real-time signal corrections, and advanced instrumentation features like real-time impedance and spectrum analysis.

Nx-Link Remote Control Interface
The system overview includes a control group, signal generation exciter, power amplifiers, and power distribution, with inputs for both analog and digital signals.
