The 800VA units deliver a three-phase sine wave output of 208Vrms continuous at 60 or 400Hz, 400Vrms continuous at 50Hz, or custom.
The CTPH 800-F7W inverters are suitable for applications that require a high input voltage, three-phase solution with low start-up current including material handling equipment, testing three-phase equipment in engineering labs, testing avionic instrumentation and other equipment.
Heavy filtering on the input and output contribute to low noise. This ensures that the inverters can be used in EMI sensitive environments without additional filtering. The input meets EN55032 Class A with wide margins; Class B is available on request. Protection features include 5,000Vdc input to output isolation, inrush current limiting, reverse polarity protection, and output current limiting with short-circuit protection.
High frequency conversion enables high efficiency, compact construction (280x67x356mm) and low weight (four kilograms). High quality built-in fans and additional conduction via the baseplate provide sufficient cooling to ensure 800VA continuous output over a zero to +50°C operating temperature range without de-rating.
Wider temperature ranges are also available. The inverters are heavily ruggedised for immunity to high levels of shock and vibration (IEC 61373 Cat 1 A&B). The printed circuit boards are conformal coated for protection from humidity and airborne contaminants.
