CS/CU-NU12AKY5W Specifications, Features & Compatibility Guide
Delivering a rated cooling output of 3450W, the CS/CU-NU12AKY5W is a 1 Ton 5 Star Inverter Split air conditioner purpose-built for rooms up to 90-120 sq.ft.in India's high-ambient-temperature climate.
Quick Answer
Yes, the CS/CU-NU12AKY5W is an excellent choice for rooms 90-120 sq ft. Its 5 Star BEE 2025 rating and 5.10 ISEER deliver up to 40% energy savings over 3-star models. Built with 100% copper and R32, it ensures robust cooling performance in India's climate, making it a cost-effective, long-term solution.
The CS/CU-NU12AKY5W suits 90-120 sq ft rooms focused on 5 Star efficiency and long-term savings. Avoid for larger spaces or if upfront cost is more critical than its verified 5.10 ISEER energy performance.
✓ Who Should Buy
- •1 Ton 5 Star performance suitable for 90-120 sq ft spaces.
- •Verified efficiency of 5.10 for reduced long-term operational costs.
- •Structural stability for consistent cooling under rigorous use cases.
- •Hardware durability via Copper coil and R32 technology.
- •Built-in grid protection with Stabilizer-free operation voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding 90-120 sq ft rated capacity.
- •Installations prioritizing minimum capital expenditure over 5.10 performance.
- •Unstable grid conditions exceeding the functional threshold of Stabilizer-free operation.
- •Environments incompatible with air conditioners physical and thermal dissipation specs.
Product Overview
Delivering a rated cooling output of 3450W, the CS/CU-NU12AKY5W is a 1 Ton 5 Star Inverter Split air conditioner purpose-built for rooms up to 90-120 sq. ft. in India's high-ambient-temperature climate. Its Variable Speed uses Variable Frequency Drive (VFD) modulation to match real-time heat load, sustained by a 100% copper condenser and R32 refrigerant circuit. BEE 2025 ISEER of 5.10 positions it among the most economical models in the 1 Ton segment, with annual consumption of 524.08 kWh. Built-in 190–240V stabilizer-free operation protects the inverter PCB without external hardware — a critical advantage in tier-2 and semi-urban Indian installations. 7-in-1 Convertible mode flexibility allows tonnage adaptation for varying seasonal load. Certified for operation up to 55°C, this Inverter Split AC handles India's peak summer intensity without compressor thermal stress.

Engineering Analysis
The Panasonic CS/CU-NU12AKY5W is among the highest-rated 1 Ton 5 Star inverter ACs available in India in the ₹28,000–₹38,000 segment, purpose-built for 100–120 sq ft spaces and delivering consistent cooling performance backed by a BEE 2025 verified energy rating. The Panasonic CS/CU-NU12AKY5W cooling performance is driven by a Variable Speed with smart speed control, adapting its output to actual room demand rather than running at fixed capacity — this reduces per-hour electricity draw to approximately 1.1–1.4 kWh and cuts seasonal energy consumption by 30–40% versus non-inverter alternatives. As an energy efficiency benchmark, the BEE 2025 rating database cross-reference places this 1 Ton inverter AC at a certified ISEER of 5.10 and a verified 3450 WW cooling output, making it one of the highest-rated models in its segment and a measurably stronger choice than most competing 5 Star options in the same price category. In practice, running this 1 Ton inverter AC 10 hours daily through a 4-month Indian summer season costs approximately ₹1,800–₹3,000 less in electricity than operating a 3 Star non-inverter AC of equivalent size — a saving that compounds significantly over 5–8 years of ownership.
