L y n T e c PDS-10 series Power Delay Sequencer
Relay based power sequencer for sound systems — Turns on front-end gear first, power amplifiers last Protects expensive loudspeaker systems from damaging power-on or power-off click & pop transients
Tested, complete package — low labor — mount next to any circuit breaker panel to sequence AC power "hot" lines
Time proven, reliable, G-E RR7P3 latching relays snap in and have low voltage plug-in connectors
Low power consumption — no continuous relay coil current
— runs cool for long life
Diagnostic LEDs and internal ON - OFF test switches speed installation for testing and troubleshooting
Cabinet and all components connected to high voltage are UL listed — low voltage electronics are isolated.
4, 8 or 10 20/30 A circuits — 120 or 240 volt models available
Up to 6 One Touch remote control locations possible
Kill function uses external contact for instantaneous shutdown.
HurryOff function shuts down immediately if you hold down any OFF button for 2 seconds.
Great for Ohh.... no........ situations.
Daisy-chains for unlimited circuit count. Interfaces with LynTec MSLC, MSP, SLC, SP or multiple PDS sequencing systems.
New Features
Multiple delay options.
Variable step rate
Completion contact option on last step can be used for additional indicators or to trigger more equipment.

SS-2 Sequencer Switch Set
One SS-2 switch set is supplied with each panel.
How they work
Applies AC to low level, frontend electronics... waits for them to stabilize... (clicks and pops are ignored by un-powered power amplifi ers)...
AC is then sequenced to power amplifi ers spreading high inrush currents over time.
Protects valuable loudspeaker systems by delaying turn-on until all low level equipment has stabilized.

This circuit breaker panel is shown for illustration purposes and is not sold by LynTec.
To avoid nuisance circuit breaker tripping on high inrush current devices, specify High Magnetic circuit breakers.
High Magnetic type breakers typically have the HM suffix such as Square D QO120HM, Cutler Hammer CH120HM or G-E THQL1120HM.
