High-energy impulses AlphaStation 200 4/233 PSU 210W can damage your computer system. These energy tran- sients can enter the system through the ac power lines or through the data com- munication lines. The AlphaStation 200 4/233 PSU 210W family of Transient Voltage Surge Suppressor products are specifically designed to prevent this type of damage. The H7007-A series, for ac power, provide fast-acting, high energy power line transient protec- tion regardless of the cause. The H7007-B and C series offer single and multiple data line suppression for both RS-232 EIA and 20 mA configurations. The AlphaStation 200 4/233 PSU 210W-D series provide complete terminal protection by combining AlphaStation 200 4/233 PSU 210W-A and AlphaStation 200 4/233 PSU 210W-B in one package. The new AlphaStation 200 4/233 PSU 210W-P series features a low profile out- line with a three-outlet distribution capability, ac power transient suppression, and a selection of data line suppressors in a wall hugging package that plugs directly into a standard wall receptacle. This new design is also available without the data line suppressor in the AlphaStation 200 4/233 PSU 210W-LB model. The AlphaStation 200 4/233 PSU 210W-M series offers suppression for up to 24 data lines in one package, with the ability to combine protection for RS-232, RS-422, and RS-423 standards.
