Ring Voltage Booster™ II

Price (per unit)

Increases the Ring Voltage to 90VAC RMS at 20 cycles

Increases Ringing Current to 7.5 REN

True SINE WAVE should make anything Ring!

The Ring Voltage Booster™ II provides 7.5 REN of 90VAC RMS Ringing to any telephone equipment wired in-series with theBooster. That's enough for more than 7 of the old style 2500 sets with bell ringers. Each of those phones uses 1 REN.

The Ring Voltage Booster™ II will boost ringing from as low as 30VAC RMS. It regenerates the ringing of the telephone line or station port, matching the ring pattern very closely. It does not change the talk battery voltage or loop current, and does not provide any audio gain. One Ring Voltage Booster™ II is required per line (a 25 Line version is available).

Boosts Ringing On:

  • Telephone Lines
  • Analog Station Ports
  • Analog ISDN Ports
  • T1 Channel Bank Ports
  • VoIP Adapter Analog Ports
  • Any Device that provides a Port for an Analog Telephone

A lot of modern telecom devices do a poor job of emulating
a real phone line, and have pretty bad ringing!

The telephone company normally provides 5 REN of ringing on a telephone line. Adding a Ring Voltage Booster™ II will allow you to put over 11 REN worth of phones on a line. Plug around 4 REN directly into the line from the phone company, and plug 7 REN into the Ring Voltage Booster™ II (which would be bridged directly to the phone line).

You need to know how many REN you're putting on a phone line or adapter. The REN value is marked on the bottom of each modern phone. Most are now well under 1 REN, although some are more than 1 REN.

The Ring Voltage Booster™ II will boost the ringing from phone system analog station ports, which often have low ring voltage, less than 1 REN of ringing current, and a Square Wave for ringing (instead of a true SINE wave as provided by the real phone company).

The ring voltage standard is lower in Europe (around 60VAC RMS), so if the phone system or device providing dial tone and ring voltage was designed in Europe, the Ring Voltage Booster™ II could be the only way to get your CPE equipment to ring!

When used on an OPX (Off-Premise Extension), the Ring Voltage Booster™ II is normally placed at the far-end of the circuit (where the CPE equipment is), to regenerate the ring. You may need aRing Voltage Booster™ II on each end of an OPX, particularly if the ringing is weak coming out of the phone system's station port and the OPX runs a long ways. You may need the Ring Voltage Booster™ II on the near end (at the PBX) if it's an OPX, and the phone company's equipment (like a repeater) doesn't recognize the ringing from the phone system's analog station port.

Has Modular Jacks for easy connection to the telephone line or station port, and the telephones.

There are no switches on the Ring Voltage Booster™ II but there is an LED will that will indicate when the ring voltage is being replaced (boosted).

The CPE equipment (telephones) on LINE-OUT will still work without 110VAC power applied to the Ring Voltage Booster™ II, but you will have no boost of the ring voltage or current. It will simply pass the line through.

IMPORTANT NOTE:  If you're having a problem with the far end ringing on an OPX, you should get the Grounded Ringing Ring Voltage Booster™ II which will work for regular Bridged Ringing (like most modern telephone equipment) or Grounded Ringing. If you're not sure, get the one for Grounded Ringing! If you don't attach the ground wire, it works just like this version for Bridged Ringing.

Comes in a plastic case with screw holes for wall mounting, and includes a 110VAC to 12V 1000ma Regulated Power Cube.

220VAC International Power Cube is available.
