Gnss Receiver; 10 Mhz Output - Safran SecureSync 2400 User Manual

Maximum power draw:
Backup Battery: SecureSync has an internal battery to support the Real Time
Clock. The battery is a small recharging lithium coin cell that is not customer-
replaceable. This battery will keep approximate time and date in a shutdown
state over ~135 days before requiring recharge. After full drain, the battery will
require ~5 days to fully recharge. Minimum battery life is ~30+ years.
Hot Swap Power Supply: Some SecureSync models have hot-swappable power
supplies and can ensure power redundancy in case of failure. Each power sled
has the same specifications as the standard AC or DC specifications (see above).
