User Manual
FAQ
What type of connections does the SP360A surge protector support?
The SP360A features two DB-25 receptacles specifically designed for RS-232 serial communication connections. This standard connector type ensures compatibility with a wide range of legacy and industrial equipment that utilizes RS-232 interfaces for data transmission.
How does the avalanche-diode technology protect my equipment?
Avalanche-diode technology provides extremely sensitive detection of voltage spikes, responding in less than 10 nanoseconds to clamp excess voltage at 36 volts while handling pulse currents up to 60 amps. This rapid response prevents transient surges from reaching connected equipment while maintaining minimal signal loss during normal operation.
What is the clamping voltage specification for this surge protector?
The SP360A has a clamping voltage of 18V DC, meaning it begins to divert excess voltage away from connected equipment when voltage levels exceed this threshold. This specification, combined with the 60-amp pulse current rating, provides robust protection for sensitive RS-232 communication lines.
Is this surge protector compliant with government procurement requirements?
Yes, the SP360A is TAA compliant, making it suitable for government, educational, and institutional procurement where Trade Agreements Act requirements must be met. This compliance ensures the product meets specific sourcing and manufacturing standards for public sector purchases.
What warranty coverage does Black Box provide for this product?
Black Box backs the SP360A RS-232 Serial Surge Protector with a 10-year limited warranty. This extensive warranty period reflects the product's durability and reliability, providing long-term assurance for your surge protection investment in critical communication infrastructure.
How does this surge protector minimize impact on signal quality?
The SP360A maintains signal integrity through a maximum shunt capacity of 40 pF, which minimizes capacitive loading on the communication line. Combined with the avalanche-diode technology's precision, this ensures minimal signal loss and distortion during normal operation while providing effective surge protection when needed.
What power capacity is listed for this UPS?
Power specifications help show where the unit fits best, including the type of load level, electrical environment, and backup role it is intended to support. These are usually the most decision-critical facts in a UPS or power-protection comparison.
What voltage details are listed?
The listed power specification is 18 V DC, which helps position the unit for the right load level and installation role.
