Q&A

1) How does a DPSV5 overcome the voltage drop along the cable when using remote powering backup? 

 The power booster is a complimentary device that connects directly to DPSV5 using a single flexible cable. The power booster compensates for any voltage drop over the trunk coax or electricity cables in a CATV distribution system, ensuring the highest voltage levels required by essential devices such as fiber nodes, trunk amplifiers, and line extenders. High voltage level during remote powering means lower current load and longer distance operation that is completely stable during DPSV5 operation.

2) Does DPSV5 need to use a power inserter for connecting to HFC networks?

DPSV5 does not need an additional power inserter. You can simply install it on the trunk cable or attach it to an optical node or a trunk amplifier. The new DPSV5 (2104) has an integrated dual power inserter (2 x 20A) that can be connected directly to a coaxial cable with an RF signal.

3) Is it possible to monitor the DPSV5 and power booster?

DPSV5 has an internal monitoring interface that measures voltage and current from all ports and can be connected directly to all standard IP monitoring systems using a single cable.

4) How reliable is DPSV5?

DPSV5 is Safecom's fifth generation power backup system started 1994 . The DPSV5’s top engineering design is based on the best and highest quality components in the market.  The PCB and connectors are designed for a 20A constant load from each port, with no temperature influence within a range of -40°C to 80°C. Our superior synchronization technology prevents any possibility of a missed synchronization or failure. With almost no devices rejected out of tens of thousands of units produced and deployed around the world, we are proud of the100% reliability we provide with an unlimited  extended warranty.

5) Is the DPSV5 online?

All versions of the DPS are designed for online RF signals during operation by keeping stable 24VDC at all active devices.

6)Do I need to replace or add power supplies in the network?

If the existing power supply provides enough current to handle two locations through DPSV5, an existing power supply can be used. However, when enough power is not available, you can replace the existing power supply with Safecom’s low–cost, energy saving dual port power supply, or install an additional non-standby power supply.

7) Do amplifiers have different voltage supplies when DPSV5 is in backup mode? 

After you install DPSV5, you can easily measure the real voltage difference between the local and remote power supplies. If the voltage difference is more than 10%, it is recommended to connect the power booster complementary device to DPSv5 to achieve the same voltage level from the local or remote power supply. 

8) How long does it take to install DPSV5?

Our latest version of DPS (version 5) supports the basic requirements for immediate installation during daytime. The most common installation is based on replacing the top part of the existing power inserter with DPSV5. This replacement can take only a few seconds, which can be done at a lower labor cost and without disturbing the call center.      Safecom is offering various housing options to support and meet our customers' needs in order to minimize the installation time.
