A power supply device that
- is designed to convert line voltage ac input into lower voltage dc or ac output,
- is able to convert to only one dc or ac output voltage at a time,
- is designed to be used with a household or office end-use product that constitutes the primary load,
- is encased in an enclosure separated from that end-use product and is connected to that product by an electrical connection, and
- has a nominal output power of 250 W or less;
but does not include a device
- that powers the charger of a detachable battery pack of an end-use product,
- that charges the battery of an end-use product that is fully or primarily motor operated,
- that is an accessory to a medical device as defined in section 1 of the Medical Devices Regulations, or
- that is a power sourcing equipment as defined in IEEE 802.3-2008 Standard entitled Standard for Information Technology - Telecommunications and Information Exchange Between Systems - Specific requirements Part 3
A security EPS is an EPS
- that is manufactured before July 1, 2017,
- is designed to convert line voltage ac input into lower voltage ac output,
- has a nominal output power of 20 W or more, and
- is designed for and marketed with equipment that operates continuously in on mode to perform any of the following principal functions:
- monitor, detect, record or provide notification of any intrusion on or access to real property or physical assets or notification of threats to personal safety resulting from that intrusion or access,
- deter or control access to real property or physical assets or prevent the unauthorized removal of physical assets, or
- monitor, detect, record or provide notification of any physical threats to real property, physical assets or personal safety, including fire, gas, smoke and flooding.
It does not include an EPS for equipment that is designed and marketed with a built-in alarm or theft-deterrent feature if the equipment's principal functions are not any of the functions mentioned above.
Manufactured on or after July 1, 2010
Security EPS manufactured prior to July 1, 2017, are exempt from the no-load power requirements.
CSA C381.1 or 10 C.F.R Appendix Z
|Nominal (nameplate) output power||Minimum average efficiency in active mode (decimal equivalent of a percentage)||Maximum power in no-load mode (not applicable to security EPS)|
|<1 W||0.5 × ln(nameplate output)||0.5 W|
|≥1 W and ≤51 W||0.09 × ln (nameplate output) + 0.5||0.5 W|
|>51 W||0.85||0.5 W|
Where ln (nameplate output) is the natural logarithm of the nameplate output power which is expressed in watts
For EPS, the use of the Roman numeral IV is accepted as an alternative to the energy efficiency verification mark if:
- the Roman numeral is clearly indicated on the product according to the International Efficiency Marking Protocol, and
- the product performance is verified by a Standards Council of Canada accredited certification organization with a relevant energy efficiency scope (i.e. offering an EPS energy efficiency verification program.)
