TPM / TVR / SVR — phase-selecting stabilizers for telecom sites 10–200 kVA
Country: United Kingdom · Model: TPM / TVR / SVR
The TVR and SVR solid-state voltage regulators rated 10–200 kVA and the TPM power control panel rated 10–100 kVA are designed for GSM base stations. The phase selector keeps the site powered even when 1–2 phases of the mains disappear.

Description
A network with deep sags and phase breaks is typical for remote towers, and in such a situation the unit switches the load to the remaining phase. The TVR and TPM have an isolation transformer with 10:1 noise attenuation, which removes interference from the radio equipment supply. The TPM combines the regulator and the site power switching in one panel, and its efficiency exceeds 97 %. The TVR enclosure has a protection degree of IP55, so it can be placed next to the container, while the IP44 SVR is better placed under a canopy or in the equipment room. The working frequency range of 45–75 Hz is designed for supply from a diesel generator with unstable speed. The unit withstands a 150 % overload for 4 min, which is enough to start the air conditioners of the equipment room.
How to choose
If the site needs a full panel with switching, take the TPM up to 100 kVA; if only stabilization is needed, the TVR or SVR up to 200 kVA. The choice between the TVR and SVR depends on the place of installation and the need for galvanic isolation; the TVR has a transformer and IP55. For sites with extremely low voltage the AVR-W is suitable, and for industrial sites above 200 kVA the AVR3AS / AVR3AE / AVR3AN series up to 2 MVA.

FAQ
How does the TVR stabilizer work on phase loss?
The phase selector switches the load to the remaining phases, so the site is powered even when 1–2 phases disappear.
What power do the TPM, TVR and SVR have?
The TPM is made for 10–100 kVA, the TVR and SVR for 10–200 kVA. The efficiency of the TPM panel exceeds 97 %.
Can the TVR stabilizer be installed outdoors?
The TVR has an IP55 protection degree and is designed for telecom site conditions. The IP44 SVR is more sensible to install under shelter.
Does the TPM work from a diesel generator?
The frequency range of 45–75 Hz covers generator speed fluctuations, and the unit holds a 150 % overload for 4 min while the load starts.
