SPA Security Amplifiers
The SPA amplifiers are 2U, 19& rack-mountable, 2-channel amplifiers. Transformer isolated for 100V, 70V and 8 Ohm distributed loudspeaker systems.
The SPA Amplifiers comprise of three models:
- SPA2060: 2 x 60w
- SPA2120: 2 x 120 W
- SPA2240: 2 x 240 W
The SPA can be powered by either a 220VAC mains supply or 24VDC supply able to support a battery back-up system for use in the event of mains failure and emergency systems.
SPA amplifiers have short-to-ground, short-circuit; overload and temperature overheat protection.
