1. What is a 120VAC to 24VDC Transformer?

A 120VAC to 24VDC transformer converts standard household alternating current (120V AC) to 24V direct current, commonly used in control systems, HVAC, and low-voltage lighting applications.

2. How Transformer Pricing Works

Transformer prices are primarily determined by:

• Power rating (VA or watts)
• Build quality and materials
• Brand reputation
• Additional features (encapsulation, surge protection, etc.)

3. Factors Affecting Price

VA Rating: Higher VA ratings cost more as they require more copper and larger cores.
Quality Level: Economy models use basic materials, while premium models have better efficiency and durability.
Market Conditions: Copper prices and manufacturing costs affect final pricing.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between VA and watts?
A: VA (volt-amps) is apparent power, while watts is real power. For simple transformers, they're often similar.

Q2: How accurate are these price estimates?
A: Estimates are based on market averages. Actual prices may vary by ±20% or more.

Q3: Where can I buy these transformers?
A: Electrical suppliers, HVAC distributors, and online marketplaces like Amazon or specialized electronics retailers.

Q4: What's the typical lifespan?
A: Economy: 5-7 years, Standard: 10-15 years, Premium: 15-25 years with proper use.

Q5: Are there safety certifications to look for?
A: Look for UL, CSA, or ETL listings for North America, CE for Europe.
