Overview

The Littelfuse PHS230A20 is a high-performance switching relay designed for precise phase angle control in demanding industrial applications. Engineered by Littelfuse, a trusted leader in circuit protection, this relay offers robust phase control protection for 230 VAC systems. With a steady-state output rating of 20 A at 100% on-time and an impressive inrush capability of 200 A (non-repetitive for 16ms), the PHS230A20 is built to handle significant transient current demands. This makes it an ideal choice for applications involving motor starts, inductive loads, or other scenarios where high initial current surges are common. The relay's variable voltage phase angle control allows for fine-tuned power regulation, ensuring optimal performance and longevity of connected equipment. Key specifications include: * **Input Voltage:** 230 VAC with a tolerance of ±20% * **AC Line Frequency:** Compatible with 50/60 Hz systems * **Output Rating:** 20 A steady state, 200 A inrush * **Minimum Load Current:** 100 mA * **Voltage Drop:** Approximately 2.0V at rated current Designed for reliability and ease of integration, the PHS230A20 features a compact surface-mount design requiring a single #10 (M5 x 0.8) screw. Termination is facilitated by standard 0.25 in. (6.35 mm) male quick connect terminals. For optimal thermal performance and safety, units rated 6A and above, including the PHS230A20, must be bolted to a metal surface using the provided heat sink compound, ensuring the mounting surface temperature does not exceed 90°C. Environmental resilience is also a core feature, with an operating temperature range of -20° to 60°C and storage temperatures from -40° to 85°C. The relay maintains performance in humidity up to 95% relative, non-condensing. Electrical protection includes dielectric breakdown of ≥ 2000V RMS and insulation resistance of ≥100 MΩ. The PHS230A20 is suitable for a wide array of industrial control systems, including motor drives, lighting controls, heating elements, and power distribution units where precise voltage regulation and protection against voltage fluctuations are critical. Its ability to manage inrush currents makes it particularly valuable in applications where equipment is frequently switched on and off. Trust Littelfuse for dependable, high-quality switching and protection solutions. The PHS230A20 relay exemplifies their commitment to providing advanced components for industrial automation and power management.

The FA and FS Series Flashers have proven their reliability through years of use on communication towers, smoke stacks, cooling towers, tall buildings, bridges and utility towers. The highest quality components are encapsulated in a rugged plastic housing with a molded-in heat transfer plate. The flash rate, ratio, and failsafe design meet FAA regulations. Zero voltage switching can increase lamp life up to ten times. The FS155-30RF & FS165-30RF include superior RF filtering circuitry for use in high RF installations, including AM hot towers. Operation: FS Series - Flasher (OFF First), FA Series - Flashers & Aux. Modules: Upon application of input voltage, the T2 OFF time begins. At the end of the OFF time, the T1 ON time begins and the load energizes. At the end of T1, T2 begins and the load de-energizes. This cycle repeats until voltage is removed. Reset: Removing input voltage resets the output and the sequence to T2.
